****** airtime

MTN South Africa (mobile service provider) has been *****ing my airtime in excess of R15 at a time on several ocassions over the past two months. When I call the customer care to enquire they tell me that I signed up for "Content Services" which I most certainly did not. When I ask them what the so called "Content Service" is and what it does, they ae unable to explain to me and rather give me another number to call. However the customer care people are able to deactivate it on their side without refunding my ****** airtime. This has been happening randomly immediately after I top up my airtime. It's happened for about 5 times in the past 2 months! You cannot tell me I signed up for a service when I know I have not done so - and there is notifiction sent for such a signup . I wasnt born yesterday. And there is no information about this so called service or what it does, so how does one sign up for an unknown service which has no benefits, yet it can be deactivated by MTN only to be radomly reactivated again without my authorisation This is unaccetable. MTN you are *******!
