No help at Iburst!

I have a problem and Iburst is unwilling to help. I have made numerous calls, asked to speak with a supervisor and got fobbed off with the same reply: - Pay up! <br> The problem....My account has been unexpectedly upgraded to a MAX25. Previously I was on the Playa5. This was also downgraded from the 10 after they called to explain that I'm not using all the data and wasting my money. I have been a loyal Iburst/WBS customer for over 13-years in total. In fact they called me recently, in February, to ask if I wanted to renew my contract - Now I dont know! <br> Imagine the surprise I got this month when the bill came for me to pay R958.20 instead of the the usual R149.00. It was explained to me that the change was made online with my password and login details. The accounts have simply said \pay\". That's it....just pay. No sympathy or empathy with a long standing and loyal customer....I asked to speak with a supervisor and I get fobbed off again. I even suggested that they supply me with the IP address of the place I did the upgrade from so I can investigate - I was told no I'm not entitled to MY Information. Must I just accept a bill just because Iburst says so? Wouldn't that be ridiculous?"
