Poor service and erroneous bill

I have been trying with no luck or success for about 30 days today for telkom to give me an explanation on the 343% increase in my data contract bill for MAY. the call centre is not helpful, i was directed to the never connected 081180 number where calls are never answered. i have been kept on hold for a total of over 3hrs in this period.

it is strange that Telkom sends an erroneous debit order instruction after i foiled a suspicious attempt by their third party suppliers to sell me a 2nd router misleadingly as an upgrade to the current contract.

When i entered into the wifi data service contract with Telkom i did not waiver my rights, they remain reserved. so i will not allow any corporation to raid my bank account. can someone at telkom provide me with answers and a bill.

the sooner i get answers on this, we can move with concerted speed in terminating the service contract
