Pathetic customer service

On 18 March, submitted my Nokia 8 for repairs at vodacom brooklyn in pretoria. After two weeks, was informed the phone won't be able to be fixed but would be replaced. Vodacom repairs then gave me a reference number as they credited the phone and need to get a new one from the store. At Vodacom Brooklyn, was informed that the reference that i was given does not appear and needs to be resolved by finance department. Since no one was giving me clear timelines when this will be resolved. I then sent a complaint to Vodacom customercare, 2 months later this is still not resolved. I have been contacting Vodacom repairs and Vodacom brooklyn store manager, to an extend the manager on 28May, lodged a complaint to ceodesk@vodacom on my behalf. Since then still no response. I have lost all hope with vodacom poor service. I do not understand, why I still support their business more than 10 years but they still give me poor service. I won't recommend anyone to take a vodacom product and I will close my accounts once the contracts expire.
