Please give me some advice

4 hours ago I received a answering message from 9722840600 @ 972-284-0600 and for some reason thought the caller was a scammer.

So I called to complain to the Gulf Coast Western and bitch.

I can't believe how retarded I am Gulf Coast Western -the oil company- was calling me back was returning a call from last months interview - telling me I got the job

How can I fix this????
