Vodacom Eastgate Repairs - Useless ********s out for robbing my vodacom insurance

Vodacom Eastgate repair are unable to fix my phone appropriately. This is the 3rd time they have it in for repairs and cannot provide me with details of the problem, they prefer to send me outrageous quotes knowing that they are able to claim from my vodacom insurance - back cover broken due to there poor repair of my phone and they charge to fix my screen and replace battery, phone came out actually worse, when i returned it they told me its the battery and screen, then when confronted that it was a return they in the next minute said it needed a software reset. I know longer trust them and do not wish to do business with them. If Vodacom sa cannot resolve this to my satisfaction then they can close my account.
