No follow up after numerous calls cut

I have tried 3 times between yesterday and today to sort out my DATA on my account through the call centre. Twice today the calls got cut and both calls were made from different numbers on my side, your staff have my number and have not bothered to call me back on both occasions. If Autopage cannot provide the service, I will cancel my contract with them!!! I am paying for a service that you are not delivering on. I have all of a sudden lost a whole lot of accumulated data on my account and have no access to emails and messages. I run a business via my cellphone and it is now becoming a big inconvenience.
