I changed my account almost 3 weeks ago only to remove:

Data 200 plan and text 600 from my Mobile account  


Then get a bill this month saying I have to pay for the data plan and the text 600...but for a month in advance?

So I've got an extra high bill.  Went on the online help and requested a response, over a week and a bit later.  No response.

What should I do?  Not pay my bill?  Not the first time the billing has been screwed up, it was screwed up last month, they discounted part of it, but said I had to pay it in full and that the discount would come off this month.

Also today I logged back into my account online and Data was reticked(text was unticked, yet I'm still charged for it) and I've changed it again to unticked.

What do I do?  Rang the 0800 89 2000 number and no one picked up...and no message to even say I'm calling Slingshot.
