Incorrect Billing

I took a contract with Autopage in September 2014 for a cellphone , ipad and a ****le . My monthly subscriptions <br> were R643,01 . From September 2014 to April 2015 I was being debited for R643,01 which is correct.<br> Then I received May 2015 bill which came to R954,57.<br> Then I received June 2015 bill which came to R4170,62 .<br> I phoned autopage and questioned why I was being billed so much , they told me that I used a lot of data. <br> I then told them that I refuse to pay this as I don't use the internet ****le . Autopage kept on insisting <br> that I used the ****le but I didn't , I phoned them again last week to question this and they kept on cutting the <br> call . For all these months I have been paying R643,01 and then all of a sudden I get Billed for R4170,62.<br> I phoned again this morning and I cut off again.<br> <br> My name is Mrs Seantha Naidu<br> Email : [Email Removed]<br> <br> Please assist me.<br> <br>
