Mweb poor poor customer service

Very very poor customer service, we moved from one flat to a bigger house in the same estate and they had to move the fibe line.. They said i had to pay a penalty fee and i was quite dine with it because it was not a year that we had fibe in the one flat. The amount was at first wrong and i emailed them and they fixed it. AFTER MANY MANY calls and emails i still am waiting for any response. My end of the month statement i received end of September was an Amount of R1300+- and it state all the reinstallment and everything with the monthly installment. But guess what they deducted an amount of R1800 and no one can tell me where is the problem and no responds on my emails
