TFG Online Shop

I ordered two pairs of Ipanema sandals from the TFG online shop. I collected it from a TFG shop near me. There were two parcels, one was correct, the other parcel contained a blue t-shirt. The information on the package was correct but the information on the inside was for Pietermaritzburg - I am in Pretoria. I went to the store the following day to return it and I received a reference number. On the 9th of October I emailed them (they were already called from the store). I was told they could not send me the correct item and that they will have to give me a refund which will take 3-10 working days. Needless to say, it is the 30th of November, I have been told more than once that it's processed but it clearly isn't. I have contacted customer care but they just referred me back to the online shop. This is the worst customer care I have received in a long time. It is nearing two months and I still have not received my refund. I wasn't the one who made the mistake but I am the one who has to send email after email to get it back. They are in breach of their own policy but that clearly doesn't mean anything to them. I am disgusted.
