No proof of out of data charges statements

<p>I used contracts for long time (about 14years) I have 2 contracts, one for my iPhone 6S (top up package plus iPhone pay off) and iPad have only 1GB contracts for R65 p/m, I used my wifi at home with iPad most of time, suddenly Vodacom charged R2800 at the end of March, I went to 3 different Vodacom service centre, I was told that I have to phone call care centre and I explained them that I'm severe profound Deaf and couldn't hear on phone call, they couldn't help me at all,I asked them to give a proof of out of data charges statements and they refused to give me proof of statements, they only gave me an invoice (account number ********** 8-3) I asked them how can they charge me without proof of statements and why they didn't send me a message that my bundle almost running out? They couldn't answer me, so I refused to pay and I sent them emails weekly and still no available today, this morning they locked my contracts and I couldn't use my cellphone at all, then I got message from Vodacom and the state said that I own them R5000, I can't pay without a proof of statements and why they over charged it, I never have any problems and only first time start last March. I can't afford to pay full amounts R5k. Will much appreciate if you can help me, thanks Kind regards Marc </p>
