MTN worst Service provider in SA

Stay away from MTN...extremely poor customer service...getting to pay your account is mountainous mission...then they team up with Nudebt...without replying to you...then Nudebt does not give you any information...their call centre is useless...they will tell you to phone back tomorrow...every flippin day...I have been phoning for 2 weeks everyday just to get a letter as proof that I am paying....still nothing...my time and airtime wasted
