Reimbur*****t owing!

I received an invoice in March reflecting that I had moneys payable to me by Telkom! Sent through my banking information on the 12th and was advised that payment would be processed within 72 hours! I then had to follow up with Telkom on the 15th and the lady in your billing department advised that she only received my information then, so the payment would take 72 hours from the 15th. It has been TWO weeks now! Please reimburse me, this is unacceptable. I will be forced to lodge a complaint at the Ombud as Telkom cancellation support and service has been really bad.
