Is whatsaround.me a Scam? Claim They Will Charge by Debit Card

I never signed up with whatsaround.me but they sent me an email saying they will charge my debit card 99.85 in 7 days. I never authorized this company I believe they got my info from mypostalchange.org which I just had a huge deal with. If anyone has any information about whatsaround.me or can explain the so-called charge to me, please do so by leaving a comment below.
