Bad customer service. I complied with the rules of a mail in rebate. I received a postcard in the mail stating I wasn't going to get my rebate because it was postmarked out of date. I know that isn't true. I called customer service and all they could/would tell me is it was received on February 20. So, because they didn't open it right away, they don't have to fulfill their promise. I followed their rules and still got the shaft. Would give no starts, but it wouldn't let me.
