MTN seriously busy with funny stuff!!

I want to lodge a complaint against Telkom. They keep on harassing my husband with the following message: "Yello. Wen sent a request to the account holder to authorize your request to subscribe to WinAirtime at R4:00/day" ( my husband is the accountholder of my phone) I never requested any of this but they send this message weekly! I went on the internet with the message and there are countless people that complains about the same thing. Lots of them discovered an amount of R3-4 per day deducted from their bank account for who knows how long and when they ask about it they say they must have subscribed by mistake! They also refuse to do refunds. Some people have a R0,50 amount deducted. This is nothing less than *****!! They also increased our contract amount without asking and when we complained they said that it in the fine print it says that they are allowed to! The day we signed the contract everything was explained to us except that!! I wonder what they do with all the money ( including those that they deduct per day without permission - obviously thousands of people did not even see it yet) because most of the places we go has no or very weak signal in times of loadshedding. In other words their service is minimal and they still seem to think to increase contract amounts. SOMETHING MUST BE DONE ABOUT THIS NONSENSE!!!
