Dissatisfied Customer

I am a very dissatisfied, disappointed customer, I have been a customer with telkom for a few years and that too a loyal one. I have been trying to contact their cancellations department to cancel both my contracts one is for the unlimited package and the other for the 12 gigs day and 12 gigs night as Cell direct marketing has the unlimited package for 299 pmand the 12 gig day and 12 gig night for R85pm and yet with Telkom I'm paying R459 + 106 and initially I asked them to bring the mins to 0 which they have not done, I spent 100 mins holding on the line, I got home before 6 and tried calling again and reached the billing department who then took my number down to send me the link for cancellations till now nothing came through. How much more terrible does the service get in this place, yet when they need the sale they phone all day after that no courtesy call nothing.
