Betrayed!!

I am very unhappy with how MTN does things honestly. I have been paying my Wi-Fi contract on a monthly basis with no fail for the past year and on this particular month of Feb my internet is suspended!? I paid it on the 22nd as per usual and my Wi-Fi keeps disconnecting. I escalated the matter and now the are telling me about a blood Turn-around time of 5 working days!!? How on earth am I supposed to work? I now have to travel to the office or buy data with which I did not budget for!! This is absolute nonsense. Do better!!
