Customer Services staff incompetence

May I urge you to please train your staff at Customer Services at your Musgrave, Durban store to more competently deal with customer queries, in this instance processing a refund. I had purchased an item at your Westville, Pavilion store, returning to the same store the following day to exchange it for another size. Having, however, changed my mind I decided to return the item to your Musgrave store on Friday afternoon, 5 July. I was informed by the cashier assisting me that your Westville store would have credited the refund amount to my bank account and recharged me for the new item and that she required both the docket reflecting the credit, as well as the new invoice, without which she was unable to credit my bank account and would only be able to issue me with a gift voucher, which I was not willing to accept. No credit and redebit had been processed by your Westville store. It was a straightforward exchange. The cashier in question at your Musgrave store consulted with another staff member, who also stated that crediting my bank account was not possible. I consequently called at your Westville, Pavilion store today and returned the item without any problems, having been informed that all that was required to process the refund was the invoice for the initial item purchased. Because of the incompetence of your Musgrave staff I was inconvenienced by having to make a special trip to your Westville, Pavilion store merely to return the item.
