Disgusting Service from MTN

I keep on getting messages to say that I have subscribed to various applications. The latest 2 are - Law4U and another one MaxLifePower. This is pure *******. I have never subscribed to either of these applications. I have in the meantime cancelled both of these applications as I simply cannot afford to pay the ridiculous subscriptions. I expect a call from MTN advising what is going on and how dare they just subscribe me.
