Account suspended

Well MTN, here we go again. Account suspended since Saturday. Again the credit limit issue. Thought this was sorted out in January. Can't get through to your call centre, as usual. Got a sms last night: You qualify for credit limit increase. This increase will prevent unnecessary suspensions. Reply 1 to accept or 2 to decline. YELLO!!!!!! UNVALUED PROVIDER: HOW DO YOU EXPECT ME TO REPLY IF YOU HAVE SUSPENDED MY SERVICE??? Does the amount of exclamations marks and question marks convey my utter frustration with you? GOOD.
