Dont Owe RCS any Money

I had a RCS account when i was medically boarded , the insurance settled my account. And my RCS account was closed . I am now getting calls and messages from VVM claiming i owe RCS R200. After my RCS account was settled in full by the insurance i never used my RCS card . Please RCS i am not well and these agents of yours keep phoning and messaging me at all times. I do not owe you any money i told the agents several times but this onslaught of calls and messages continue. Please bring this to an end.
