Sneaky charges they can't explain, query #***

My latest dealing with MTN support centre, and the online team on Facebook has gone from pathetic customer service to a whole new low of sheer incompetence!!<br> <br> Since 7 October I have been trying to resolve a query I have, namely incurring PSD charges on my cellphone, while I clearly have 100's of MB's of Internet data bundle still available!!
