Phone suspended for no reason

Yesterday (2015-05-02) my line got suspended for no reason. I tried phoning MTN customer care but what a waste of time. Seems there is no one working there because you wait forever on the line. I then went online to MTN site and wrote a email explaining my problem. Within 2hrs the phone was ready to use again. Today (2015-05-03) i am having the same freakin problem. This time i went in store for help, that was even worse because they told me that because of payment that was made on 30th of April it does not reflect on the system due to public holiday and weekend. The just sat there and dialed 808 which i have done already. Did not even try and solve my problem. Is this the kind of service we can expect from MTN in the future? (customer care and in store help) I had the same problem last month. This month same story. Line suspended for no reason. I have 2 accounts with MTN but only one gets suspended. Service and help is pathetic and useless.
