Who called from 8642831050

I want to know if this is a legit number. It was given to me to be the name of Michael Richardson as the person who bought my timeshare

I been in contact with people at this number, the Richardsons, Jada Richardson called and said her and her husband were looking to buy our timeshare, if you can call them back and see what they say.. I wonder if they are trying to run a scam on us.
