Vodacom very bad service

I upgraded my contract bigging of October with the Vodacom shop in Kollenade. Where within the first two weeks my brand new Samsung S8+ started having a burning smell. I returned to the shop 3x times on the same sunday where I had to fight with them just to take in the phone and send it in for a report. The manager Timothy told me if there is anything wrong they will replace the handset. Having logged numarous complaints at Vodacom and customer care I waited 9 weeks where the managers at the Vodacom shop in Kollenade told me Vodacom does not need customers like me eventualy they told me the phone had been fixed. Then I got it back without the screen protector which I paid R600 for and I must test the phone after they replaced the battery, motherboard and LCD screen. 4 days later I phoned Viera the Vodacom shop manager to tell her the phone is in a worse contition than the first time i sent it in with more problems. Stefan and Timothy told me they wont replace the phone it is my problem and I must wait until when ever it is fixed. They never followed Vodacom's procedures. Also on my new contract they are charging me R350 handset fee for a handset I still don't have and they don't have answers for me as to why I am paying the R350 per month as they explained to me that I don't pay for the phone on my specific contract. After numerous complaints and phone calls to Vodacom Customer care the decision to replace the phone lies with the Vodacom shop and there is nothing they can do for me. Vodacom keeps making promises they will sort out the issue it has now been over 13 week without my phone and still not resolved. They say they should have replaced the phone but that's how far the matter goes. Still no phone or answers and no way to cancel the contract.
