Multi-Media Portable Projector and DIY Projection

I have bought a Multi-Media Portable Projector and DIY Projection Screen, for the amount of R1299.<br> The payment was made on the 08.12.2015, up till now, I have not receive any proof of receiving my payment or acknowledging my deal.<br> I have send 2 emails since then, and only once did they came back and told me to wait 10days before confirmation of sale.<br> I have then send another mail, with Rudolph Nyakatawa (Groupon Customer Support - EMEA) , telling me that the projector is on its way.<br> <br> Since then new deals of projectors appear on their website that was cheaper than my deal, and today I see again that there was possibly the same deals at an expensive price - Did I miss something ?<br>
