Overbilling

On the 5th October I reported an error on my telkom mobile account and received reference number ********** 3. I was told that I would hear from someone within 72 hours. After a week of hearing nothing, I called again to be told they are escalating my query and that someone again would contact me. This has continued weekly with me phoning them and receiving the same story and still no correspondence from then. At one point I was told that Tony Venter whoever he may be would be contacting me, again nothing. I phone to speak to Tony Venter and after an hour of being on hold, I gave up. In the meantime my phone service has been suspended as I refuse to pay an incorrect amount. I am now not benefiting from my services of free calls, data etc but am sure will be expected to pay for this down time. I run a business with this phone and find it totally unacceptable. This is my 4th year with telkom mobile and the firsat time I am experiencing this inefficiency. I am due to upgrade my contract in December but how can I consider that after this treatment. My bill has a spend limit so I pay roughly the same amount every month. I have had the same services on my contract the entire time which includes an amount of free data etc etc, now instead of the usual credit reflecting on my account for the all inclusive, they have failed to credit which is the reason for this over charge. I have noticed that this error has come into effect since Telkoms billing system as changed. I have always been the first one to defend telkom when others have trouble but have now experienced the poor service first hand and couldnt be more dissapointed. I have also been in contact with the Facebook page but get the same story.
