Unsatisfied Vodacom user

I have be with vodacom customer for almost plus minus 31 years and Took out a new contract got the wrong phone but I was fine with using the phone. the phone was faulty and I have returned and inquired about the faulty phone that I am still pay for monthly. (6 months already)It has been sent away 4 times to vodacom repairs in polokwane and they said new parts have been put in… so if it is a new phone why should a new phone be opened and parts be replaced… I am still not able to use the phone since it is still not working and it seems to not gonna be resolved. With this phone being sent away so much and me not having a spare phone , I had to take out yet another phone contract make my expenses double now. -unhappy client
