United HealthCare Services review: Hard copy of leaving service not sent

I filed for leaving your company on October 06, 2023. I was infprmed that I would be receiving a letter to send to my pensions division showing when I was being released from your customer care/ service. I waited for the 2 weeks, then called back, spoke with a very nice woman she said it should have been sent on the 9th or 10th , yet no letter was sent.My coverage was ended on Nov.1, I've called back several times and been left on hold by 1 woman who was insistent that I had to wait the 2 weeks for a different letter from 10/30/2023,The email I received was not the letter saying when my coverage would end. Im now without coverage ,because someone on your merry end cant do what they were supposed to do. I have all my records, and just as you do I record everything because I have severe memory problems. This is for my use only though, I dont and wont use them that way. The longer I have to wait the more problems I run into. My wife isn't a patient person, and my patience is at an end. Today is 11/03/2023 and that means you are close to 2 weeks past the time I should have received my paperwork. Next place I have to go to of course would be the BBB, then of course the News paper here in Las Cruces, bad publicity and all, I liked your company I really did, but if you treat people like this that are leaving it shows a bad character flaw in you. I dont want that for anyone, and from what pensions has said its not just you folks
