CELLPHONES REPAIRS AND REFUNDS

Hi, my daughter bought a cell phone at Ackermans. (the other daughter bought the same phone at Edgars). This phones proof to be faulty, and was sent in for repairs at Cell C. Cell C declared the phone as "un-repairable" and do we have to exchange the phone. We went back to the store just to find that there is no phone there in stock that will suit my daughters needs and we requested a refund. The manager was very rude and told us that they do not do refunds. And I must call head office myself. I called Cell C, explained the situation and they said that Ackermans must refund us. Still Ackermans refused to refund us. On this stage we will be forced to take a phone that we do not want or loose our money. The "store policy" of no refunds was never explain to us at the store, and I feel in this situation it is not very fair. Ackermans can not provide us with a exceptable exchange.
