We found the return address on their terms and conditions, but during my phone call to them, they were adamant that I was out of the time limit and could not return it. I told them that the packaging was damaged and no paperwork or instructions for use were included.
I printed out the emails that I sent to both companies, well within the time limit, stating I wanted to return the goods.
Our credit card company are taking it up and we asked them to cancel our card and issue a new number, which they have done.
Fingers crossed and waiting to see
Certainly won't get caught again !
