Poor customer service and mislead customers

Customer service at dischem Kayalami corner is appalling. The lady working at customer service is so rude, Her name is Dorcus. I am not sure if she understands the values of TCF. I returned an item on the 12th of August and I was advised that my money will be returned to my bank account within 2 working days (by a Dischem employee) . I made the purchase using my debit card and they said they would refund the money back to my card. Today is day 2, so I get to the store and I go to customer service and I find a lady named Dorcus, as I was trying to explain my issue she dismissed me and told me to go get a bank statement, which I did, upon my return she told me cash office says it takes 7 days, and I should go away( without even looking at the statement), Still shocked, I then asked her why was I given false information, without even answering me, she called a fellow staff member to get the manger and said to me she does not need stress, I must deal with the manger. I asked her why is she giving me attitude, she looked away and carried on doing her own things. As a customer I am in disbelief and I have never seen such attitude, especially when The store is at fault. The store mislead me, and when I need assistance I am being met by a staff member who is put at Customer service but does not know how to treat customers. The store could have given me other options for a refund on the 12thbbut they insisted the refund into my easy zero debit card would be successful and my money would clear in 2 days. You can not give a customer a turn around time and then not met the customers expectations. My bank has told me that specific card I used does not allow P.O.S payments, the transaction will bounce back to the senders account and that could take up to 30 working days. I have told this to the store, and I am not willing to be inconvenienced because of the stores *********** staff, who can't give customers accurate and true information. I need my issue sorted out, and I need the behavior regarding Dorcus at customer service addressed.
