PATHETIC SERVICE!!!!!!

MASSMART more like MASSART in taking your hard earned money! Purchased a new Pool Cleaner R946,00 from Builders Warehouse Sunninghill, asked the teller if it does not work can I return for refund? yes sir,,, (reason I asked is it is a new make on the market) surprise surprise it does not work at all! this was 5pm so I re packed and returned the following morning, asked for cash back as I need to try Makro etc, as Builders has no other brand, Lady advised they cannot give me cash has to reverse on the credit card, I advised the teller did not tell me that when I asked if i can return for refund, gave me the slip and advised I go to the teller / supervisor. Teller & Supervisor confirmed as I used C.Card they can only reverse it takes +- 7 working days for the refund, i said not acceptable as I cannot wait 7 days to buy a new pool cleaner? and I need the cash back, Supervisor (very abrupt & rude) simply says thats their policy, so I asked where is a sign indicating this? she says teller should have told me, so I advised I asked the teller as it was a new product can I return for full refund, she said yes, Supervisor simply says sorry not her fault and reversed the amount on my C card. I asked for the store manager she just points t o the centre of the store and says go there! I explained to the manager (they know me as I shop there weekly) my situation and he says the Supervisor should have called him and he would have give me the cash refund,,,,,, well now THEY have my money for 7 days earning interest on my MONEY!!!!!!!!!! I have been shopping there for over 10 years!!!!! never again I will go support MICA from now on,,,,,,,,,,,,
