Shocking service from Homechoice who take your money but won’t assist you

homechoice - any assistance?!? I ordered and paid on the website of Homechoice for a duvet set of R1199. I received an email from them thanking me for placing and paying for the order on the 21st of September. I noticed however the delivery address was incorrect and on phoning them they said I should pay an extra R75 delivery fee via eft and they would then reroute the delivery to their Pretoria showroom. I duly did so. The initial amount shows as having gone off my credit card on the 21st. I have since then been in a constant battle with their customer service as they say the amount does not reflect on their banking system and I need to provide them with proof of payment. I contacted my bank who gave me the credit card department who said because I entered my credit card details on their website the only proof of payment they can give me is a bank statement. I duly provided this in pdf format as requested by the Homechoice customer service (joke)agent (important details blacked out for security of course) only to have the same customer care agent now tell me this is insufficient and they cannot help me. End of story. No amount of requests for it to be escalated or to speak to someone in their finance section are responded on.
