Pensioner dissatisfaction in customer service / unauthorized billing

I am extremely displeased with the level of service I get from your network provider. Once again I have been billed for R393.99 where as my normal bill amounts to R208.99. I have no knowledge of the rise of amount debited and when I call your customer service they advise ots for data.

I have not authorized to be billed for this, your consultant has the audacity to advise me thT I will be billed a further R600.00 as a penalty if I downgrade back to the normal bill.

Please note I am a pensioner and cannot afford these ridiculous charges.

I expect a refund and no further charges to go off my account without my knowledge.
