On Air

I'm not happy with service I received. From On Air they gave me offer for Explorer I accepted it as it was nice offer our aggrement was to debit R160 every month which I never had problem with it,there was this other month they debited twice with 2 different references number I had to reverse 1 debit order which I don't know the references number I picked up the phone and phone them they said maybe there s something wrong they will fix it since then they never debit from my account up untill in the month of January 2021, the end of last month they debited R800 from my account which when I calculated all the month they stopped debating it doe not even make R800 now they have stopped the service from my Explorer, On Air service is very poor even their agent cannot be able to assist when have problems WHT I want from them is to open thee service or refund back my money I'm tired with them I cannot keep on calling wasting my airtime while at the end they cannot resolve my problem
