I had submitted a deed correction request on November 7th. I called last week (week 3), and they said it would take 3-4 weeks to process, and to try and call the following week. I called yesterday and at first, the woman told me they were busy, and that it would be 6 weeks. She put me on hold to see which batch they were processing. When she came back on the phone, she told me it would be 8 weeks. She said this was one of their busier times of year. I checked the website again today and it looks like the change took effect, so either they are now processing requests that came in around that time, or they moved me to the front. When I talked to her, she said they were working on the batch that came in on Nov 2nd.
I bought a resale back in early November. The deed was recorded on November 30th. I expect the ball is in Wyndham's court now. I don't expect them to be done before February.
