I just got a call from these guys today - 18882261322 (number is already on BobRTC: https://bobrtc.tel/phonebook/dial/18882261322)
So, I called them back and a guy that I talked to introduced himself as “Tony” and he told me that he’s a worker of a company called “american shopping benefits”. Of course he asked for my full name, mailing address and my credit card details because “To claim my reward I had to handle a processing fee of a $1.95…” (゜-゜)
I have managed to get their website from him. This is the address that he gave me - https://www.myshoppingbenefits.com
