Frustrated Dissatisfied Services

I have just about had it with MTN and the incompetency to treat their customers fairly.Endless issues with them which has resulted in me taking drastic action, however, I still have not receive feedback. Since my account was taken over from Nashua Mobile I have had countless billing issues. I come from Nashua having had certain services given to me.And telling me that my account is taken over my MTN I would expect the same service from MTN.I had a call limit in place, which I MTN does not offer.Why take on client if you are unable to provide the same services or better yet communication to be in the first month informing me about how I will be billed would have been a better and proper idea. However,I have to take time out of my wrking day to call you and find out why my line has not been suspended which normally is the 2nd week of the month.Only come to find out, no limit was placed on my account'.I will not be left liable for something which I had in place with Nashua , I would expect the sama data to be taken over by MTN. Instead I have a huge debit order taken from my account EVERY MONTH and when I call to query the amount no one has the capabilities to answer me correctly.
