Good result they paid up within 5 days of my email, note the company was Bulgari not the country Bulgaria!

Hi there, I would very much appreciate some advice, I am acting on behalf of my sister. For explanation of her situation I will copy an email I sent last Friday. I sent it to all the emails she had. I also phoned bulgari head office in the uk to try and resolve this. They told me bulgari Ireland ltd (incorporated in Ireland) manage the heathrow operation. I have sent this same email to all permutations of the directors names (received off irelands version of companies house). Email (names and contact info removed) Dear Sirs I am writing to you on behalf of my sister who worked for Bulgari as a supervisor from June 2011 to end of May 2012 at Heathrow Airport. She would invoice Bulgari for £1,833.85 per month basic salary on top she was entitled to to a commision based on overall sales at the airport. S left Bulgari at the end of May due to pregnancy, with the attached 2 invoices outstanding. (4 months and 5 months overdue respectively) April invoice totalling £1,043.53 (taking into acount days taken off) May invoice totalling £1,833.85 S understands from SH's corrospondance (S's line manager) below that it is agreed that April would be paid at the full monthly rate of £1,833.85, due to Bulgari's failure to pay the invoices on time. S is therefore outstanding £3,667.70 plus any commision she earned from 1st January 2012 to 31st May 2012. S is a new mother, since she gave birth to her son on 14th July 2012. As I am sure you can appreciate this is a large amount of money for anyone to have outstanding for such a long period of time, let alone someone who is going through the stresses and costs of starting a new family. At the moment I have not seen a copy of the contract that exists between S and Bulgari, nor I have I seen evidence of remmitance advices, acknowledgements or purchase orders that you would expect from a normal client - contractor relationship. I have no experience in contract or employment law but my instinct says that the relationship between S and Bulgari is actually closer to an employer - employee relationship. Which would bring the additional responsibilities as provided for in British law. As I am sure you will be able to tell from this email, I am not an expert in this field. However I can promise you that I am stubborn, extremely focused and I have a lot spare time. Should S not receive payment within 7 days (or a considered response as to why she is not owed this money) we will take the following actions. **1. We will take action in the small claims court in the UK. Seeking*payment of this debt. **2. We will write to Heathrow Airport Limited explaining how S has been treated **3. We will write to UK and Irish newspapers, and Media organisations*explaining how S has been treated. (it may not seem like a big story but you never know it may get a small mention somewhere on a slow news day. **4. We will contact an employment law specialist, to consider the question of whether S could be considered employed by Bulgari. *All S is looking for is what she has earned, please can you confirm that payment will be made (and how much) within the next 7 days. Including any commision she has earned this year* S can be contacted by email or phone We trust you will contact S by return explaining what your intentions are. End of email I fully intend to follow through with the actions I have threatened above. But I am a bit stuck as bulgari are referring me to this Irish subsidiary. Can I send freedom of information requests to their Irish address to get a copy of her contract? Can I send a letter before action to the registered Irish address, then start proceedings locally in the uk? She did work solely in the uk after all. Any suggestions/ ideas on how to proceed would be very much appreciated Cheers Daring fire
