Faulty line

My internet was working perfectly. Yet suddenly it cut. Thinking it was MWEB, I contacted them only to realize that my telephone line was dead. I lodged an online complaint (***), written on Facebook and Twitter to them. Only to be told that my complaint has been escalated to their technical department and they apologize for the delay. It's been 41 hours now and I still don't have Internet. It honestly is ridiculous that it takes that long to solve an issue. It's one thing to tell me they'll update me shortly or what not. But it doesn't help when they promise but don't deliver. Shortly, in my opinion doesn't take days. I get that they are many faults (obviously they need more technical staff to rectify the endless complaints I've seen online). But it would be pretty helpful if it didn't end up costing me over 5GB (just under 1k of money I've now wasted.) of data in one day and counting to just do the bare necessities that my job requires. I do wish their response rates didn't just end over instant chats on Facebook and Twitter but rather delivering what's promised.
