RMI has called multiple times after XXXX, even after XXXX, despite being informed that the matter is contested - charges for medication insurance ( after date of cancellation ) that had been cancelled because the insurance had ceased medication coverage! RMI was told the billing was contested, with request for the names of their officers/owners and those of XXXX Mmedicare RxSaver Plus PDP who apparently sent them the bogus charges and instruction not to contact me again until that information was provided. Not only has RMI not provided the requested material. Not only has RMI continued to contact me, but now they are repeatedly contacting me after XXXX. When their telephoning individual is informed that they are calling after XXXX, they are refusing to terminate the call.
