Most useless cellular supplier EVER!

I have been trying to get Autopage to load my data bundle correctly onto my account and pass a credit for the incorrect billing since I took out this contract. Every month they keep billing my data from my normal account and not the bolt on data plan which I am getting billed for. Each month they say that it has been done and that they will calculate the credit amount to pass and when the next billing cycle comes it is exactly the same. Their billing and customer service department is the most useless bunch of people I have ever had the misfortune of dealing with. I will never recommend Autopage to anybody ever
