Useless service

I am tired of the poor service from vodacom specifically fiber internet. I had a fiber account which was not working yet I had to pay for it through their lawyers. They have to change debit as requested however when I raised the issue they tell me to call their lawyers. The account was paid, I have three months requesting to simply get my paid up letter, they keep sending me from number to number. Hai this is out of order really No! I don't recommend their fiber services at all
