Negligent staff

I requested that I be contacted back from the Telkom Mobile Callcentre on Tuesday the 06/02/2018 at 10:40am, I was contacted back by an agent by the name of Portia who assisted me in applying for a device, she completed the application and advised that it would be delivered to me. A few minutes later she called me back to advise that she was not sure if the colour I wanted was in stock (rose gold, iphone 6s) and that she would contact me back, to this day she has not contacted back, I called into your callcentre this morning to follow-up on my order and was advised by an agent that my application was not reflecting on the system at all.

This is highly concerning for me because I had given my banking details & I.D number to this person a credit check was done on my profile so why is it that there is no record of my application on the system?

Also, the agent that i spoke to advised that if she should assist me ANOTHER credit check would need to be done on my profile so thats 2 credit checks in a matter of days and MY profile will be negatively affected because of YOUR agents inability to execute their duties in a professional manner?

I either want my order to be re-instated with the information i provided to your employee with all my requirements that is specified on that order or I want the check that was done on my credit profile to be reversed and proof from transunion or cipro to be provided to be confirming this or I will be laying a complaint against Telkom with ICASA.
