Breach of Contract and pathetic customer service

A few months ago I too 2 contract with telkom mobile. I signed the contracts for R199 each unless I purchased extra bundles of course. Everything was good regarding my bills up until now. Suddenly they have now added a spend limit on my account which I never agreed to, I didn't sign for it nor did I opt into it in any other way.I now have R220.50 extra added to my bill after being told that my bill will never amount to more than R199 as my minutes and data are capped and if I purchased more I would need to call in or use the self serve option. *******ly Telkom thinks that they can now **********ly add services onto my account without me knowledge of it??? I wrote a complaint about them on Hello Peter, but never got contacted to resolve my complaint! I called into the call centre and spoke to Sinenhlanhla who "logged a query" for me n gave me a reference number, I asked to speak to a manager and waited for about 40 mins on the line before the advisor dropped the call on me. Chances are, they don't respect their customers enough to contact us to resolve complaints, but for anyone who reads this, Telkom has definitley lost any lotalty they ever had in me and I beg of other potential telkom customers to take my complaint seriously as this is the worst I have ever been treated by a company. I am 7 months pregnant and certainly don't have the money nor the time to stress about this. I am absolutely disgusted by this ***** and customer service!!!!
