Vodocom isbworst service provider ever

I upgraded one of my contracts in order to suprise my son for his birthday. Recieved the I phone 8 and immediately battery life was dropped to 20% after a full charge and continuues full charge from draining... Within two days of recieving the phone I contacted them and requested for the phone to be collected... Its been two weeks and im still sitting with the phone which battery life is messed up. Every Consultant gives me a reference which at time when i try to track with courier company it doesn't t exist... And everytime a different reference number. They refuse to let me speak to a team leader or manager. I have 4 other contracts with them and going to cancel. All of them when they expire... Vodacom servuce is disgusting and i knownoonger want them as a servuce provider. Hello Peter please upgrade rating and including a 0 start rating and - 1.
