Le Morgan has listed my name as in Arrears ,after I settled their account 3 months ago, they also have Agents that are Rude and harass Clients demanding payments that was made 3 months ago

I called Le Morgan in June and asked about the Settlement amount, I was told I had to pay R1489.85,which I gladly paid on the 13th of June .By month end of June, they went on to debit my account, this is after I paid them off , I then reversed their debit order ,because I don't owe them anything. They went on to list me on Credit Bureau and said my Account is in arrears ,I was also contacted by their Agents who are rude and they harass Clients, I also told them that the account is paid and I don't owe them anything. They have debited me again twice more , since I settled their account . This is a warning to other Clients so that they make informed decisions, Le Morgan treats clients badly and they keep *****ing from clients ,way after you paid their money ,they will still debit your account . Right now my credit score has decreased and I am unable to take out credit because Le Morgan has listed me as in Arrears, whereas they have been paid 3 months ago , this abusive behavior from Le Morgan is unacceptable
