Unhappy Client

I am so disgusted with the service since the 3 years I've been with vodacom. For the past 3 weeks i have been calling back and forth and all i receive is bad service. I took my contract phone in that i have with them since 2019, my first repair was with them in 2020 and now i needed to repair my phone again and the insurance require proof that i did the repair only for them to tell me they updated their systems, they do not have proof as they are using a new system, after i emailed them several times and guess what NO reply i mean what happened to backup systems?? i am utterly disgusted with the service i would not recommend anyone to make use of vodacom in fact i will not upgrade with them, they systems suck and have staff that cannot assist you in the best possible way.
