Telkom won't upgrade a contract that I have had for many years

After being a customer with Telkom for over 9 years and having 7 different contract with them which are always paid on time, my one contract came up for renewal and I put in an order to upgrade my contract. The order was sent for vetting and declined due to "affordability". The contract I app**** for is cheaper than my current contract. I then tried applying for a devices even cheaper that the other and it was declined again due to the same reason. Apparently, when you pay your account on time and in full, you are not considered a valuable customer. I suppose I will need to cancel all my contracts and find another provider for my phones, iPads, Macbooks etc. I am fuming this morning and Telkom is not on my happy list. This is unacceptable. Even to downgrade an account that they incorrectly upgraded to a higher plan, required vetting. What!!!!!!!!!! So you want to vet me to pay less on a contract for a phone and less on a data contract. I am absolutely shocked at this shocking service!!!
