interesting/upsetting phone message

[disney queen]

i am not real sure if this is the correct board; please move if needed. when i checked my messages friday, there was one from a timeshare broker letting me know that there are 2 possible buyers for my DVC. only problem--they are not for sale. the upsetting part is this person asked for my husband, who is deceased, and me BY name. i googled the phone number and it is for universal timesharesa. i do not know how they got my name and number. i called DVC administration, but they were already closed for the weekend. these properties have been in my name only for 3 years. any thoughts???
