Telkom does not want business!

I have been calling telkom almost everyday to sort out an upgrade which I booked two weeks ago. Everyone tells me they will get back to me but to no avail. I have checked on line for the progress of my order but it has not been logged. Also I have been wanting to change my banking details for my debit order, but they keep on telling me that the system does not want to accept my account from FNB and that someone will call me back to arrange it, but no-one ever does. this has been going on for a few months now, and every month i have to pay an extra R180.00 for a debit order that does not go through on an account which I am no longer using. This is absolutely ridiculous!!!!!
