I am being billed for charges that MTN cannot explain. Check your itemised billing people!

<p>For the past two months I have been trying to get an answer out of MTN for a mysterious monthly charge of R21.93 which gets billed to my account every single month and the number they claim it is charged to is 686. Please note that I am on the Sky package so national sms's should be included. Now upon doing my own homework, 686 is not a valid number so how can I be messaging it? I checked to make sure that I am not subscribing to any content services as well. I contacted MTN on 26 July, again on the 8th of August after I received no reply, I got a response from Lethu Duba on the 15th of August not resolving my query and asking me to contact another department, I logged a new call on the 16th of August (ref ********** 42) and today on the 26th of September I had to call back to be told that the query raised on the 16th had no answer. Now I have another new query raised (ref ********** 98) and still nobody at MTN can explain to me what this charge is for but yet they are charging me for it. And on top of that it' been almost 3 months and my query is still not resolved. MTN, is this a bad joke? Do I also need to put up a billboard to get service out of you people?</p>
