Hextom: WhatsApp, SMS & Push

Had my whatsapp number registered with Hextom, but for some reason the app wasn't capturing any subscribers, I asked several times for support to check, which they said their team would investigate, waited for about a week and still nothing, then asked for them to de-register my number, which is about another 4 days and still nothing (which means I paid for a phone number and now its stuck with hextom).
I was really willing to use the app when I read the other reviews, but with this support I'm giving up
