Mweb and their couriers can't get it right

I signed up for mweb and told them I didn't have an ID document except for a temp ID as our house burnt down. they charged me for delivery and monthly fees twice yet ccd couriers either didn't pitch on time or didn't make notes about the ID. Yesterday they phoned to schedule the delivery again I told them the situation and they assured me it could be delivered. Today the guy was an hour late. And then wouldn't deliver. So I cancelled my debit order. Mweb quickly emails to let me know they can't take the money. There is no way to email them and calling their call center uses all my airtime and the calls get dropped. I'm so unhappy because I have a remote online job and am spending so much on pay-as-you-go lte. I needed this but it's been a nightmare
