I bought a injection pump in March 08 was wrong pump, they told me to send it back for a refund, I did and they have never sent my money. Its now Oct. 08 and still have not got my $2,100 dollars back and can not get them to answer my call. This is the worst company ive ever seen. If anybody is looking to get their money back let me know. My email is dewest15@yahoo. I will be taking action soon. The owner is Jeff at etr for anybody who has had a problem and the number is 865-776-1976. If enough of us call maybe we will get some action.
