DebtSafe Poor Service

I opted out from Debtsafe in 2020 due to unprofessional manner they treat their customers, the first problem is that you cant get hold of anyone through telephone, by Emails their response takes forever. I managed to pay all my debts on my own but now I am struggling to get a clearance letter from them, I sent an email and was rep**** by request of paid up letter for 2016 which I believe it was their duty to call that company as I was still their client by then, I have managed to get the 2 paid up letters they requested, now I'm advised that turnaround time for my enquiry is 1 to 2 weeks. I am now stuck as my new employment has required that clearance letter before Friday (18 Feb 2022) this means I'm *****ed. I have never felt so useless and depressed in my life.....now I have to watch my career flushed away just in front of my eyes.
