I called to pay a bill for K U Physicians , and when they tried to transfer me to a 3rd party to pay with a cc, the call dropped . Then I got two calls from the above number. When I Googled it , I was shown Mc Kesson corp., out of Lewiston Maine . Yellow pages description says they provide " solutions to reimbursement inefficiencies" which means they are the 3rd party credit card processor for payment if you pay by phone. I 'd just paid online ,so I ignored them.
