Russell verualm reversal of payment

My name is Buhle Ntuli I made a lay-be of built in furniture at Russell's verulam I was assisted by an elderly, professional sales man, I told about the terms and conditions since I did not have enough cash to pay for the ward drobe I asked him if there is any other payment methods that could help a customer like me who does not have enough cash he told me that I can lay-bye, he decided to take me around the store and showed me all kinds of ward drobe they had in store I told him that I like the built in more than the others, I decided to pay an amount of R650.00 and the rest will be pay in monthly instalments, my sister passed away so I could not continue with the payment due to financial difficulties I had encountered so I decided to go to the store and ask them to reverse the money I have paid back to my bank account when I arrived at the store it was the beginning of April I was told that the stores system was offline they will make a copy of my ID since did not have my original slip since my bag was ****** agent took down my name and told me that he will capture my details and send the request to the head office I must wait for 2 weeks my money will be reversed back into my account up until now the money has not been reversed its been a month and 2 weeks nobody bothers to call to give an update at the store. I decided to go to the store myself to find out what's happen everybody was so busy they could not assist only thing they did is take down my details and I was told the same bull***t story that the store systems were offline that's why we could not assist on time I then asked if Russell is such a big store for a month their IT department is doing nothing about the system for a month and 2 weeks it would of been professional for someone to pick up the phone and call clients with queries to apologies about the delays that's what I call customer service. I'm no longer going to shop at Russell's ,Checkers House and Home is much better bulls**t service given by Russell's company must close down officially.
