Cant get a hold of anybody,been on hold for hours

I am emigrating at the end of the month, and have been trying to get hold of Telkom Cancellation department to terminate my land line and ADSL subscription. After spending over an hour of accumulative time on hold, being repeatedly told about \high call volumes"that my call might take a while Please wait for the next available operator. I am honestly under the opinion that they purposely do not answer the call as it is for canceling the account. <br> I then decide I will go to my local Telkom branch and cancel it in store. I am promptly told by the lady that she cannot process my request"
