Inmar promotion services didn't honor rebate submission.. ripped me off. del rio texas

Bought waterpik showerhead at home depot because of $10 rebate.  Submitted the rebate form, upc code, and original receipt.  They send me a post card stating: offer denied because upc code not belong to a valid manfucturer, (how I would get my hands on a barcode that belongs to an invalid manfacturer completely defies logic) and offer form was not submitted. (another outright lie).  I wrote to the rebate center and suggested that their employees, must be submitting bogus barcodes and stealing the customer rebates.  If I ever get an answer, I'll let you know.  Never buying waterpik again.
