Rude and insulting. Credit Merchant Services. I told her I was not interested. SHE CALLED BACK IMMEDIATELY FOUR TIMES!!!! Caller ID says Sierra Vista. Did not know who I was and said she was calling with a change in my merchant services account. I take Credit Cards, but not thru a traditional merchant services account, so obviously it was not a call concerning my account. Probably a SCAM looking at the other posts. Rude, Rude, Rude!!!
