Disgusting customer service

I was not sent a statement indicating the shortfall from medical aid for bloods taken. Yet was contacted by Lancet collections regarding an outstanding amount. I them requested a statement. A statement was sent and a payment arrangement was made of R2000 pm and I paid via the channels on the lancet email. Received numerous emails and smses that I was behind on payments and "ignoring" Lancets calls (daily calls and smses). After I sent through proof of payments AGAIN than nothing.
