Telkom over billing

It's been almost 2 months battling with telkom, I called to downgrade my internet package, the consultant then added the subscription as an additional subscription. I received my bill immediately contacted telkom was trf surely 6 times on the call then was told to call another number . I called that number and again consultant's kept on transferring me saying that they not the correct department.i received sms notification on the 27th Aug with reference number but today the 30th still no call from telkom...I am actually disappointed that it's taking so long to resolve an error that the company/consultant made.
