Terrible Customer Service

This is the forth complaint that I wrote about to hello Peter and bestmed seems not to be taking my complain serious. The last response was that the issues has been escalated to management, I am now receiving unending emails from ER24 threatening to blacklist me. This is turning into a nightmare. EMAIL FROM ER24 Dear: REJOICE BALOYI Client Ref No: GN***

Urgent payment required on your ER24 account that has been handed over to Saya Recoveries for collection.

It is recommended that you make a payment by 25 June 2021 on the outstanding balance of R2568.00 to avoid further action from our client.

Settling your account could help: Improve your credit status, increase your chances of securing future credit facilities at other credit providers and avoid being adversely listed with the major Credit Bureuas.

If payment has been made please forward proof of payment and quote *** on your email in the subject line to ensure payment to be allocated to your account.

Can someone assist me with this because Bestmed was supposed to have settled this a long time ago
