Useless service

Absolutely useless company. I keep getting calls and sms' regarding an Ampath account. This dates back to 2018. I know my accounts are settled, but to avoid any further harassment, I called them to say I would settle what they say the amount due is. I asked for banking details, the lady promised to sms them to me. That was last week already, am I going to wait another 2 years for a reply. I want to settle this once and for all, but you don't get any response from them. Very Frustrating!
