Sucky service

Horrible!! Seriously? I downgraded, then my normal debit order didn't go off on the new amount (but it was fine when I'd upgraded before) and my service is cut. So I go online with my phone, fix the payment, set up the debit again. Today my account shows paid... router works... YET NO INTERNET AT ALL FOR 3 DAYS!! I've tried whatsapp multiple times... useless contact method, honestly. Then I tried phoning - an hour and a half to hold?? I work from home, this is the worst service you could have given.
