Scandalous service from Homechoice!

I placed an order in the last week of May & paid with my card. The order took more than the 5-10days they advertised & subsequently cancelled the order. I spoke to a Melisa at the call centre was told my refund will be processed to my card within 72 hours. The next day I received an sms stating my refund has not been approved & called the contact centre. Needless to say the agent was unhelpfuly when I told her the story & the reference number for the call. Now I am being given the run-around with my refund. I cancelled the order because nobody could give me a date on when the order will be delivered. The agent even agreed that the delivery date of 5-10days advertised is misguided. The poor level of customer service for this company is shocking and all I want now is my refund - its been a whole 4weeks and still nobody can tell me when my refund will be processed!!
