Didn't hear anything about "Wayfair" (I did buy from this site a few months ago) The ID simply said Provo UT and the voice mail mentioned something "free samples" an to call back. No idea who this was.
Legit wayfair number, called from their business verification dept to check if an order I placed was for business or not...apparently my account was flagged for business orders, they wanted to verify so they could remove me from business-oriented emailings. Completely legit
A woman from Wayfair called and left me a voicemail stating she had questions about what type of business I have (I don't have a business). I ordered a gift from their website last night. She also said she would be sending me an email. I specifically did not check "I am a business" when ordering so not sure why they called.
This is a legitimate business, but they are trying to get you to join their business plan. You decide if you want to answer the call, but rest assured it is legitimate.
