Horrible service

I would like to cancel my account as the service that I receive is very poor. The internet service cuts out regularly and very often I do not even receive important messages. It is impossible to get hold of anyone at your company as I am put in a queue for the longest time and there is no way of even accessing my account. Furthermore, my bill has increased, yet you are running a special of R399 per month but I have to pay R629. Please cancel this account.
