Please tell me who is calling me from this number. I have sent them money, and now they want more. Claim to represent Sitco Communications. Any help appreciated.

Am waiting for a call from them to my google voice number i contacted them about a loan and they sad they'll call back.

Responded to an ad placed by Sitco Communications RV Tranport. Got a call from this number and now am curious if this is a legit representative of the aforementioned company since it does seem that Sitco is a real company.
