I also purchased from them off eBay February 2020 and it took almost 14 months to resolve. The first unit fell through for some reason and they offered me a replacement to choose from in their portfolio, then with respect to the replacement unit, the seller used the 2020 and 2021 usage (after estoppels and as/after the deed change) and then tried to stick me with the MF for the 2021 week that they used which was supposed to be mine. In the end, Resort Transfer Group did right by me. When I informed them that their sellers used my 2021 week and stuck me with the MF’s, they contacted Marriott and paid for it with their own credit card. We literally wrapped this up just two weeks ago. I was certainly concerned and frustrated at times but in the end it all worked out. If not for the pandemic, I may have been upset about losing the 2020 and 2021 usage but since I didn’t have to pay for it, I’m pretty happy with how it turned out. During the last couple of months, Brianna was my contact person there and she was lovely to deal with.
