I am sick and tired of Telkom Mobile attitude!!!

We sign contract for wi-fi service with Telkom Mobile service in september 2013.Same moment we was cheated to sign on 5 YEARS contract instead 2 YEARS as everyone else.From the start it was problem with their accounting department as we was paying cash every month but they keep breaking in to our account ,taking double payment that way,or we have pay penalty every tine R 100 if there is not funds.We hardly get it right.Then in february 2014.we took Laptop from them on contract also but they PUT TOGETHER THOSE TWO CONTRACTS and again keep breaking in our account or cutting our wi-fi signal if we didn't pay both. amounts in one.From october 2014 we can not receive emails on that same laptop as is saying that,,can not find provider;many computers shops
