poor customer service

i tried applying for a new contract with mtn (mind you, i don't have any contract with mtn) but i get a pop up message which reads "there is an open order on this account. a new contract cannot be added at the moment as there's another pending order that needs to be completed. in the meantime, an agent will be in touch to assist you"

1. an agent hasn't contacted me for a month now 2. i went to the store and apparently i don't qualify for any mobile contract 3. one of your agents contacted me on the 6th of August to go through the application with me and it was approved 4. i contacted you the following day to change the delivery address and the same agent canceled the application completely and attempted to apply for a new one which declined 5. he then said he will contact me again, which he hasn't.

now i want to understand why mtn says i have an open contract with them when i clearly don't???
