Terrible Service

OnAir TV has debited my account twice this month. I have never missed a payment before. I phoned their call centre but the call is ended before you can speak to an agent. I have sent an email to enquire about this issue, they have not responded nor acknowledged receipt of my email. I sent a WhatsApp mess to their WhatsApp line, but the message was undelivered. I am not happy with their service at all. I have been a good customer to them but they continue to give me bad service.
