Ackermans Westgate - Worst Retail Cellphone Service Supplier

Please do not buy a cellphone from Ackermans. They have the most horrific service in South Africa. I spend about R15 000 a year at Ackermans Westgate and as from today I have decided to have no dealings with them anymore. I bought a dual sim Hi Sense cellphone in May. I have had endless problems with the phone and when I went in to the Westgate branch the Manager (Msulo) was the worst help I have ever received. They acknowledge the fault with the phone but refused to swop it out because we didn't have the box. We have the phone and the receipt (WHO KEEPS THE BOX LOL). He told me straight and was rude about it that he will not swop it. Now we must sit with a phone that we paid for that is broken
