Inmarrebates.com advertised that I would receive a rebate for a Nivea lip care product Del Rio Texas

I bought a Nivea olive oil and lemmon lip care product at a CVS. I sent inmarrebates all that was requested.  My original register receipt, with the price circled, my information.  Now 6 weeks later they have the nerve to send me a postcard stating I will not get my $2.99 rebate for the purchase of LYPSYL product because the register receipt was not submitted. This is an absolute lie. They have a space on the post card to call but no phone number is listed. They tell me to resubmit along with the post card, it's impossible to do that when they have my original receipt. I will advise consumers not to purchase any products with this decitful company, Inmar Rebate Center.
