South West Engines They sent me the wrong motor, they picked it up and will not return my money Wisconsin

February 7, 2013, I contacted Southwest Engines for a motor for my Jeep, they charged me when I received the motor it was the wrong one.

It took over a month for them to pick up the motor, I have sent several emails requesting my money back and finally sent them an email gave them until May 1st. 

When I call they are very rude and most of the time do not answer the phone and when they do answer they  immediately transfer your call to a voicemail.

I need them to returrn my money has I had to purchase another engine from another company.
