Bad Service

I am not someone that usually complains, but my experience with Vodacom over the last 4 months have been absolutely absurd. I upgraded my contract at Vodacom Tzaneen lifestyle center in Feb, to a Samsung S10. About a week after I received my phone, it completely crashed, "System modem crash" was the message on the screen, I phoned Samsung and they advised me to take it back to Vodacom. Vodacom Tzaneen lifestyle centre informed me that they would need to send the phone away minimum 21days but they are not able to provide me with a loan phone, this wasn't a option for me as I use my phone for business. I then took it to 2 different Samsung as well as Vodacom stores with no luck, they all just did software updates and said it should be fine now. I then took it to Vodacom repair centre in Centurion Mall, they advised that they would need to do a complete wipe and reload of software, which they did it took the entire day. This still didn't fix the problem, the phone still glitches and doesn't perform as it should. Vodacom Centurion did not log the repair and is unable to give me any proof of the work they have done and said this was my problem not theirs I can bring the phone in again, I live in Limpopo so this will be a 5hour drive. Vodacom Tzaneen can't assist me with a new phone as they need the reference from Centurion, and the only option they are giving me is to send the phone in again, but still they can't provide me with a loan phone.

I am at the point where I am going to cancel my contract and request a full refund for the last 4 months paid.

This is absolutely ridiculous.
