Poor Customer Service from HOMECHOICE

Still waiting for Cash Refund 2 weeks later! I have been a homechoice customer for the past 10 years. I recently purchased a 2 seater couch on a cash basis for R7100, and cancelled the order due to the fact that at time of payment I was requetsed to pay an amount of R7100, and 5 days later the customer services department requested me to pay an additional amount of R289 for assesmbly for not calculated. They were unable to tell me why the fee was not included intially and after requesting to speak to a manager, I was told someone will call me back. Of course nobody called me back, instead I have been given the run around for the past two weeks, with excuses such as, "we have a backlog", "we are unabel to transfer calls to team leader", "it takes 5-7 working days", "your refund will be processed after we receive your babk statement"! I submitted the bank statement more than 4 times to ***. The customer service is shocking, when I asked the consultant if I owed homechoice money, the collections depatment would be hounding me, and hand over my account. My money is sitting in omechoice babk account accruing interest for homechoice, will they refund me with interest? Until now I am still awaiting the team leader to call me back
