Contract declined because I complained about poor customer service

I was once a contract customer to MTN back from 2009 to 2012. When I was applying for an upgrade in 2012 for a new phone I was told the phone that I wanted was not in store and that they had to order it. The consultant at the time told me the phone will be delivered to the store within a week and that I would be called to sign documents and collect the device.

After waiting for almost 2 months with no one to contact me with feedback on the availability of the phone, I cancelled the application due to very poor customer service. I had not signed any contract yet.

Fast forward to now in 2020, I app**** for a data deal. My application was declined not because of missed payments or not being credit worthy. ( I'd always paid my premiums on time without having a single lapse). My application was declined due to me cancelling the contract application back in 2012 due to the horrible service i got!!

I have never heard of such nonsense of an application being declined because I complained about poor customer service over 8 years ago when I had been a loyal payer when I was with them all along!

I'll definitely take this as a sign and take my business elsewhere if MTN wants to be childish because I complained that they do not take care of their customers.
