Ackermans Polokwane stole my phone

I bought a cellphone end last year and within a month it gave me a problem. I took it in the store, it's been 3 months now and everytime I have to take a taxi to Polokwane to check the status and they say my phone is still at repairs. O I know they are taking advantage because they think we are from a rural area and we can't complain. The level of service is so bad and I am dealing with *********** people. The manager doesn't even have the repairs con tact details.
