Hi all, I'll try and keep this as short and sweet as possible... I took out a Three phone contract last year, I didn't get on with the phone, I sold the phone to a company called 'The Big Phone Store', I then purchased a new phone and used the sim card from my contract in this new phone. End of September this year I lost my phone, I contacted Three on live chat to inform them, I gave them the IMEI number of the lost phone, they blocked the phone but for some reason they also blocked the phone I sold. I had to keep chasing them for a 'proof of block' for me to provide to my phone insurance company, it took them around 3 weeks to finally email this to me, when I received the proof I realised it had the wrong IMEI number on it, I contacted Three again and told them this, they said they had blocked both phones, I told them they needed to unblock the phone I sold which they said it would be unblocked within 72 hours. In the meantime I received a letter from 'The Big Phone Store' giving me notice of intended court action. I emailed them straight away and explained the situation and told them the phone would be unblocked within 72 hours. They agreed to hold off court for a further week. They then emailed me a week later and said the phone was still blocked, I checked this myself and noticed that this was indeed the case, I got back onto Three and they apologised and would put the unblock request through again. In the meantime I have now received a County Claim form claiming for £900 for the phone plus their admin charge and £70 court fee so £970 in total. This was not my fault at all as I gave Three the correct IMEI number to block but they took it on themselves to block the 2 phones. I have proof of the chat transcripts to confirm this. This is the first time I've received a court letter so I'm really not sure what to do.... is there anything I can do to fight this as it wasn't my fault. I even emailed a copy of the chat transcripts I had with Three to the company, I was working with them to sort it out but I feel like they've rushed into the court route. Thanks for any advice, it's greatly appreciated.
