Incompetence

I had actually been a client of Jacklin for a while . I purchased books from them. After becoming a student I could not afford the subscription so I phoned and cancelled it. I had an outstanding balance which I settled in March 2018. I received no mail from them then suddenly out of the blue in July I was sent a sms notifying me that I was handed over to NRB risk for collections of unpaid account. I phoned Jacklin and spoke to someone called Andre and he said to e-mail the copy of the payments which I did and that it would take 24hrs to resolve but received no response. I then got a email on the 6 August 2018 from Sandra from Jacklin telling me that payments were received but no apology from them. 7 August 2018 received a call from NRB risk asking for payment and I told the lady the account was settled and she insisted that I provide proof. I told her to get in touch with Jacklin and they will provide the proof she needs . She said no i must do that and she said well she can't help me . I told her that I did not ask for help and was not prepared to provide proof as I already sent the details to jacklin . She responded in return by saying I was handed over. I am very upset that it was through their incompetence I could have been blacklisted and not even a apology for causing me this grief.
