Fibre internet down and no one at Vodacom can fix the problem!

Our fibre internet went down 3 weeks ago and it is has been one mistake after another from Vodacom, after first reporting the issue, and being told I’d be sent the SR number which never arrived. Then the next day my husband called back and they had no recollection of the SR number and provided another. On the Monday I then got a call to say the problem had been fixed, only to get home and realize nothing had changed. Then on the Tuesday I got an email saying the case was resolved and closed, which it wasn’t. Wednesday I queried this and got no response. Thursday I called again and they had no reference of the problem being unresolved. Then I got another SR number. Eventually someone worked out the Mac address associated to our modem was connected to someone else's account. But since then they haven't been able to fix it. We then decided to cancel the Vodacom service and go with another supplier. Only to find out there is a 30 day waiting period before we can switch over. Which now means we need to wait a further 4 weeks before we have internet again. Not having internet at home for 7 weeks is simply unacceptable. I haven't had one response to my email communications and have followed up numerous times. I am at my wits end now. I don't know what to do as no one can help us and we can't wait 30 days before having internet again. Vodacom you are useless.
