Unsatisfied customer

I bought a phone at Ackermans the phone gave me a problem on the first day of receiving it, took back to th store they gave me back my money, they advised m to get a phone that is more expensive as th previous one to prevent having the same problems. The second phone that I got is giving me problems clearly something is wrong with their phones now they are saying they can only refresh the phone or take it into repairs.. I had to call the head office to have this sorted out but haven't received any feedback. Nothing hurts like having to pay for something but the quality of the product is not up to standard
