Billing and ALL ROUND ATROCIOUS SERVICE!

I left the country 25/12/15, my talkom number was not in use, so my contract amount (R499) should go off as normal, from the 01/02/16, nothing extra (data, minutes) were bought. I get a bill for R697, which was subsequently debited off my acc. I have been trying since then to get someone to contact me, they don't have a direct email addy, so I used Facebook messenger back and forth till at one point I was bluntly told to complain to HELLOPETER if I had an issue with not being contacted.This was on the 05/03/16, On 07/04/15, Nthabiseng Phasha finally contacted me via email, apologising for only replying then, explaining my previous case was closed due to no contact! I showed her my invoice and also explained I need to send my phone in or repair, but the POP is in CT in storage, I got the bluntest response \You correct the information can be pick up on the system however bringing you proof of purchase and ID is the requirement to book device for repair\" , She also says, After looking at my invoice, that my balance is 499 but my other invoices show extra data bought, what does that have to do with anything?? I was billed 697 its in the invoice! with no reason as to WHY! "
