Telkom sucks

Worst customer experience ever. First I cancel 2 months ahead so that there is no delay. Then after that I see they still deduct with increased amount. What a **** service. Then I try to call them and the number on their site is not available. Tried the customer live chat and it keeps on kicking me out. Obviously they are hard up for customers and make it difficult to cancel contracts. Sort this out Telkom this is such a bad experience
