Cell phone service has been suspended continually

Service initially suspended on 13/4. When I queried I was told payment had not been made. I queried this with Discovery and they assured me the debit order was never lodged. When I re contacted Autopage I'm told it's due to load shedding, but they'll resolve the problem. I am then reconnected and 2 hours later the service is again discontinued. This has been going on for days and no-one at Autopage is able or willing to deal with the problem. I demanded to talk to a team leader at mid-day today and the gentleman told me 'problem solved', BUT 2 hours later ..... NO SERVICE!!!!!,. I have just been reconnected, but who knows for how long. I am due to leave the country on Saturday and have no idea how to get this problem resolved, because clearly this service provider really doesn't care about customer service.
