Radiolize

Am now at well over a week waiting to hear back from Radiolize- have not even received a “hey, we received your emails”/ support ticket…
So at first I was happy- bought a tier 2 a while back, it worked as it should. Bought a 2nd tier 2 this most recent time they were back. I wrote them while the Appsumo deal was still on on about migrating my second account into the first. WITHIN 24 HOURS I received a response that it could be done but I would have to wait until after the Appsumo promotion was over (I kept the email/ support ticket). AFTER the promotion was over I replied to the support ticket and received no response. I then contacted them via their support contact page- unfortunately I can’t prove this because I never received confirmation that they received the email. Now that the deal is over are they even responsible to keep their word? I definitely would return my second tier 2 if possible…
