Non-responsive after airtime went missing

Signed up for Afrihost prepaid mobile data and airtime. Four days later my airtime disappeared without me making a single call and I still had data left. I have numerously tried all of Afrihost's support avenues (called support, created ticket, email and WhatsApp) to get to the bottom of this. The last two weeks I get no response, despite me begging them to respond. Even the threat of putting my complaint on HelloPeter.com did not motivate them to respond! I signed up with Afrihost as I was under the impression they put the customer first, but alas, I was wrong.
