Vodacom - bad service and bad customer care

I really didnt even wanted to give a star for this review. Lately i have been struggling with Customer care at vodacom (online and in store). I sent my phone in to have the battery replaced, when i received it back it was not working properly. I sent it in again from a different store, not thinking it would cause confusion as everything is on a system. However, they sent the phone back without any report or quote or call, saying i should give the phone in at the store i gave it in the first time. Now, all this going back and forth has caused me to run out of my 3 month warranty and i am going to have to pay for the phone again. This couldve been sorted out if vodacom employees would just call back or update you on the situation, but they keep making promises that they cannot keep. Another problem is that we have contracts that has been renewed on our name that we have not signed for and we query it they cannot tell us if there is even a signature, and we have had a situation where a contract was taken out on our name of which we do not even know who the person is. i am dependent on calling customer care for any queries as i do not have time to sit in a shop and wait for someone to help me, but this makes me very disappointed as i cannot even rely on the customer care employees to give me a call back when they promised.
