SHOCKING TREATMENT OF ACKERMANS/ TENACITY!!!!

So I know times are tough and there is a national lockdown in place and some services are limited but ENOUGH IS ENOUGH! I have been with Ackermans since 2012 and never really had a problem with them unless it comes to paying your account online and not cash at a store. so in March 2020 I requested a settlement letter as I wanted to pay my account in full - Ackermans gives me a letter with their banking details on and GIVES the ref number that should be used. so for about 3 weeks I still keep getting these SMS's saying account overdue ect, now I'm wondering how can this be? I have paid in full, I've send POP but still I get these messages. So finally I get a lady to help me - I resend her the pop and all, I get feedback that payments was not allocated to my account as Ref was wrong??? so I send her the settlement letter to prove that it was Ackermans that provided the REF and not me, any who she sends it to her team leader / manager as wow all of a sudden its allocated. Now the best part happens for truly the WORST EXPERIANCE / TREATMENT ever!!!! on 03/05/2020 I go to the nearest Ackermans to me - I go to the till and ask them to check my balance...……...my card declines???! the manager phones client services and after being on hold for what felt like an eternity the lady comes back and says the account was closed as I am on debt review????!!! its like sticking a hot poker in my ass right there!! who the f@@k closed my account? why was I not informed? and who the f@@k said I was on debt review?? I have never been in my life on debt review!! still now on the 04/05/2020 @ 18:20 pm I have not received any responds from Ackermans?? Oh and gets this - Ackermans didn't update to say account paid in full so now my credit score has been affected as well with their absolute stunning work!

at this point I am disgusted with Ackermans!
