Thanks for my TPN record!

So wanting to rent another property and I got shot down twice. With the 3rd try I manage to find out what the reason was, me being declined. Never skipped rent, always on time and make sure payment is made in FULL. To my surprise Janine from ***lin flagged me on TPN because NOT PAYING AFTER THE GRACE PERIOD on TPN. From a grade A tenant to a B. This was last year, after ***lin forced me to hand over my house keys to the landlord after I paid for the full month and decided to move out in the middle of the month. This already left a bitter taste in my mouth as I paid in FULL. They listed me on TPN because one month they could not "find" my payment and Just proceeded to list me. No phone calls... no whatsapp... no email with regards to this. I only found out now by accident. So I call ***lin. Thembi sent me a email saying they cant update it was a MISTAKE on their side. TPN says they can. After back and forth and losing my temper, Paula said she will need to get a username and password to fix ***lins MISTAKE which I now cant rent my dream home because I look like a slow payer or bad tenant. After 20 min or so Paula let me know they fixed it, little to late!!!! DONT RENT FROM THEM unless you wanto sit with a bad TPN record!!! I am livid!
