Medicare is a jungle. I was told that since I had been on Medicare before getting it again would be no problem. That statement was sooo wrong.
Three times I told Medicare that my address had changed and three times they said "OH no problem, we'll update it."
My address never got updated. So my card went to my old address. Took them MONTHS to get it to me at the right address. Then I get a bill for my Medicare premiums of $895.00. For like months they sent my premiums bill to the wrong address. So they sent me a lump sum bill for all those months I missed because they sent the bill to the wrong address.
