Business ProfileforGeisinger

In May 2023, I received a statement from Geisinger dated 5/15/23 (invoice # *********) stating I owed Geisinger $160.60 with no specific information on the date of service or provider. Immediately upon receipt of the statement, I called billing customer service at the number provided on their website asking for an explanation. My Geisinger online portal showed my balance was $0.00 and has been for some time, I was told there were issues with their billing system, and they changed providers. As a result, they were updating the customer's accounts, and if I wanted to talk to someone for detailed information, I would need to call the number on the statement. Note - the number on the statement is transposed from the number on their website. I thought it was a scam. Skeptically, I called the number. They said they could not provide information over the phone other than the date of service was from 2020 and insisted I pay them $160.60. I asked they send a detailed list of payments I made from Jan 2020 through current. I finally received it today (6/25/23). None of the amounts match what I faithfully paid between 2020 - 23 (well over $2700.) This amount does not include what the insurance paid along the way. In addition, I do not recognize the providers' names on the 6/25 paperwork, nor have I been to Geisinger medical center Danville. It also states "admitting provider." I was not admitted to any hospital. I am now not only concerned that I paid excessively more than what was due, it truly seems my Geisinger financial records are mixed with someone else's! I will not pay the additional $160.60 from 2020 as I cannot agree I owe anything further. I was on a financial settlement plan that I worked hard to get down to $0.00 for yrs. All of a sudden, I received a statement saying I owed more? My online account showed the balance going down and finally down to $0.00. My banking statements are proof. Their records are completely wrong. I challenge and say they owe me a refund.
