Billing

Telkom has been my service provider for almost 4 years and lately they trippled my bill for December without me allowing them to increase my limit and when I questioned it, I was given explanation that didn't make sense something that hasn't happened before and neither was I warned about that's if they came up with new developments. I have since asked for the termination of my contract but no one has contacted me its going for a full month now. The service I am receiving its pathetic I feel as a victim of theft. The coverage is terrible as well.
