still waiting for my refund from Lewis store (orange farm)

On the 13/10/2017 i purchased a washing machine worth R5000 and payed via EFT , although i did get notifications on my phone i was told that the machine can't be released to me because payment did not reflect on their system, i refused to leave without my washing machine and was told that if i can make a cash payment the machine will be released to me and when the EFT transaction reflect on their system ill be refunded as long as I bring bank statement as proof. The following day 14/10/2017 i submitted my bank statement which showed both the EFT and cash withdrawal of R5000 each, i was told that by Monday 16/10/2017 the R5000 will be refunded into my bank account,,,,,even today my money has not been transferred back into my account,,,,,whenever I call i got send from pillar to post,,,,,,no one seems to take responsibility.......My name is Johannes Nhlapo and my contact number is ********** 033
