Telkom non debit... No compassion... No attempt!

I have a mobile contract with you and you decided to jot debit my account for 6 months you then slapped me with a large bill after which I paid after paying my bill you slapped me with a larger bill??? Really??? You have jow handed me over as I had stopped paying due to the ridiculous amounts you requested monthly.. I ensured to have enough money monthly tk be debited as per the contract agreement however telkom did not keep their side of the agreement which is not my fault... Telkom never apologized for the inconvenience never bothered following up now i would like to make arrangements to pay telkom should contact me to do this as I have been inconvenienced I have been slapped with a large bill due to their incompetence.. BTW this is not the first terrible experience with them.... The land-line service is just as bad if not worse... I want the issue sorted at no extra cost to me i want a resolution and an arrangement that suits me considering I was the one thrown in the deep end by TELKOM.. I WANT A RESOLUTION!
