arrears paid,no service

We paid the arrears with three months in advance. This payment was made on the 26/01/2015 and proof emailed to [Email Removed]<br> We have tried for three days to get Iburst to reconnect our service. We have been sent from one person to the other at their call centre,its become very frustrating to get the service reconnected. I work from home and rely on the Internet. This is not acceptable from iburst.
