BAD Service

I bought a Samsung grand neo + on 26-09-2015 and it had mic problem took it for repairs on 08-10-2015 at the vodacom repair agent Alberton I was informed that the phone repaired and ready, I collected on 14-10-2015 when I got home the phone had problems connecting to the network to it back to the Vodacom repairs and spoke to Shaun who is the manager he gave me attitude, false information (telling me that Vodacom has a network problem and that two towers are not working asked him for proof from vodacom that there is network problem he couldn't provide me with the proof and when i called vodacom customer care on my collegues number I was told that there are no network problems that they know of)
