Incompetence of Busamed Accounts and Collections Departments

I am having a bad encounter with Busamed. My partner underwent a procedure at Busamed Paardevlei facility. The medial aid only paid part of the account and I had to pay the difference.

I paid the outstanding amount on 07 February 2024 and then received a SMS on 14 February 2024 from their collections department advising that I should contact them urgently regarding the outstanding amount. I phoned their collections department on 14 February 2024 at 14:33 and they confirmed that they received the co-payment amount.

To my surprise, I received an email from a recovery firm, Fusioncs on 04 April 2024 advising that I should contact them urgently regarding the outstanding amount (which was paid on 07 February 2024). I tried to contact them via telephone numerous times, but neither Fusioncs and Busamed Collections department answered their phones.

I emailed proof of the payment to Fusioncs and Busamed Collections departments, on 04 April 2024 and requested proof of receipts of the email, but neither of the companies responded.

I obtained a copy of my latest statement from the Accounts Department at Busamed on 04 April 2024, which clearly indicate that the outstanding amount is R0.00. I forwarded this to both Busamed Collections department and Fusioncs and requested receipt of email, but again neither responded. I again tried to contact both companies via telephone multiple times, but no one answered their phones.

Email addresses I sent the emails and proof of payment to with no response or confirmation of emails are: ***; ***; ***; ***.

How does these companies even operate if no one answers their phone or respond to email? Now I am worried that this will reflect negatively on my credit record, just because of their incompetency.
