Suspended services for month to month contract

Took home wifi about 4 months ago. This was suppose to be month to month, meaning if I dont pay that particular month I wouldn't have service. March and April I had no services as they were suspended because I didn't pay. I had no problem with that because well its month to month contract. Problem came when today 17th of April I went to MTN to pay so the services could be put back on, I paid full R480 for my home wifi and was told to restart my router and services should be back up in a few minutes. 2 hours later after restarting my router more than 10 times I went to Musgrave MTN to enquire what's going on only to be told my services would be activated after 30 days. How because this is not a fixed contract. The services were suspended because I didn't pay. Now still I won't have wifi even when I paid. I need my services reinstated.
