Unhappy with saya recoveries, I need my paid up letter

😫I’m having an issue with saya recoveries, I have been calling them requesting for paid up letter for MTN account. They been promising to send it through email till today they say they gonna send it, now I’m having an issue I can’t open any account due to Blacklisted account from MTN and I paid all the money twice they keep on saying I’m owing but I’m done paying and I need that paid up letter to remove my name from red dot on MTN account I need to do things🥺🥺why saya recoveries you do that to me

I’m so unhappy with their services
