Shocking Service and non delivery of goods bought at Sportscene Walter Park!

My son took his birthday money to buy a pair of socks on his debit card. With only R300 left in his account he used his bank card. He bought a pair of socks for R175 from Sportscene Walmer Park and the transaction was processed and the amount deducted off his account. Because Sportscene had no paper in their card machine.. The confirmation did not print. . They then tried to put the transaction through again twice after that but with my son spending the last of his money on the first purchase the next two attempts obviously declined and he was told he could not take the socks as they did not have proof of payment. If he had more money in his account they would of deducted an EXTRA R350 off his account. I took him back the following day and was told to bring proof of payment from the bank which I did. After now waiting another half hour only to be told that the money is in Sportscene head office account and not in the account of the store where I bought the socks from so they could still not give my son the socks. This I find unacceptable as it was the shops mistake to begin. There were no apologies.. We were just told to leave again even after giving proof of payment from an original bank document and the store admitting the money is in the account but in head offices account which I do not understand as that is not out problem as they did the transaction with their machine in the Walmer Park shop. The salespeople should assist and Management should be jacked up and their non existent customer service improved. This was not an enjoyable shopping trip. No apologies just told to leave and come back in 5 to 7 days (after my 3rd visit to the shop) Pathetic service!
