Voucher missing

I bought 2 vouchers that I have not used yet. <br> I lost my printouts and went back to the site to reprint.<br> Forgot my pasword, tried the reset numerous times but no e-mail received.<br> <br> I managed to sign on eventually, but no vouchers are showing under my name.<br> Tried calling, but just a voice recoring plays and then hangs up.<br> The recording gives an e-mail address which we can not make out.<br> <br> How do I contact GROUPON for assistance?
