debted for services that I did not ask for.

I received a message at 3.43am on wednesday 19 September 2018 for gamezboost. First of all I was sleeping so no I never requested it. Secondly I called the *464*970# to opt out which you can't because it kept on saying invalid request. Then I dialled 135 numerous times and was never put threw to someone to help me.

How do I get rid of something I never asked for? I am so unhappy and am thinking of just ending my connections with MTN as it is always a issue with everything .
