Jose Crespo

I've been contacted by a Jose Crespo. I sent him a link to the snakes available. He then emailed me back that he was sending payment. I quickly emailed back to ask him which snake he wanted so I could hold it for him. I never got a response. He said he was sending a Cashier check so he needed my address, and phone. Continuing to ignore several requests to ID the snakes he wants? Now I get a phone text that he over paid by mistake the agreed amount. There was no agreed amount. He said to cash it, and he would tell me what to do with the overpayment. This screams scam to me! Has anyone else been contacted by Jose Crespo?
