Erroneously billed 2.5k in data charges twice!

I have been erroneously and I surmise, deceptively billed amounts of R 2,500.00 twice in data charges. Communicating with MTN for the past four months has yielded no satisfactory reply or actions. <br> <br> MTN has been continuously trying to ****** funds on a debit order from my account, I had lodged a query into the erroneous amounts and also explained notwithstanding, that I am by no means able to afford these charges as a pensioner. The amount being billed is outrageous, with a spike from R 99.00 to R 2,500.00 in Data . I have been an MTN client since the inception of mobile phones and my charges have been consistent throughout these last 12 to 18 months, with no significant usage changes.<br> <br> Upon further investigation, I have found that I am not the only client experiencing this absurd overcharge with what I can only believe to be fictitious claims to supposed internet usage. <br> <br> My contract with two numbers has now been suspended and I am unable to receive any sort of clarification other than a generic email response. The billing and accumulation in data charges is questionable to say the very least.<br> <br> Kindly readjust my amount owing and release the suspension on my contract.
