Shapiro Shaik Defries & Associates disgusting and disrespectful

I had a arrangement with SSDA re MTN account, in May 2024 they gave a settlement to paid in 3 months and gave me the amount to be debited for May, June and July and agreed on a debit order mandate. After paying for my July payment, I sent an email to request for the statement of account. Only to be told that I still have a balance of R722.30 which I requested call recordings but I was flatly ignored then I decided to let it go. I paid the amount they said was due on 31 July 2024 to avoid incurring further interest on the account. This morning I woke to an email saying I owe the R0.01 how when you said I owed R722.30 which was paid? Are these the delay tactics you use on customers? Emails and calls go unanswered. I just want my paid up letter. Your service is disgusting and disrespectful. Benny Mosiyoa and Nompucuko Mdyeshana who I believe are the Team Leaders/Supervisors or some leaders in their department do not acknowledge correspondence at all. What a *** organization to deal with.
