Disappointing Vodacom fibre service, billing, and overall customer care

I have fibre with Vodacom. I then moved houses in March this year and did inform them and requested migration. I got the fibre installed into the new house and everything was ok. It was only July when I received an email stating that I was owing more than 4000 rands and when I enquired,I find-out that I was getting double billed for the old house and the new one. I send numerous emails and make lots of calls. I was without wifi for over 4 weeks. I’ve been having the same problem since July and they have currently disconnected my line again due to non payment of arrears caused by their error of double billing. I will never recommend Vodacom to anyone. They are slow to resolve problems and have they do not take customer care serious.
