Rude Consultants that don`t want to listen and they don`t update proper messages.

i had settle my stuttafords end of February. Thabo was the consultant that still email me the new banking details. i dispute the account in January because there were charges for late payments and payment was on time. it was decide by Thabo and his senior to settle it if i pay the R250. and that i did end of February. INn the week of lockdown the calls started and they insisting that i must pay R250 still. And i am tired of explaining the same thing over and over and then get the phone put down in my ear. i am emailing Thabo because that is the only email address is have but i am getting no reply. Saturday i got a call and the lady was saying im disputing the account and i explain to her and she said ok. but again just now they phoning again and being rude.
