Vodacom - non existent service and holding my fiber line ransom

I have a 10/5 meg uncapped fiber account with Vodacom. I requested an upgrade to 100meg fibre on the 29th of March 2018. I had to send numerous e-mails and make numerous calls to get this upgrade to take place. Eventually after a tedious process I accepted the quotation. Since then I have been informed that the upgrade is complete. However it is not complete, and needed to make many calls and e-mails to Vodacom to explain that the speed is still not the same. Each time I speak to a custom representative they spin another story (send e-mails or send screen shots etc etc) and eventually I get e-mails saying the order has been migrated. And then the entire process starts again.

I have done the above more then three times now, and still no luck. I then requested that Vodacom release my line to the holding pool so that I can move to another service provider. And was told that this also needed to be done by e-mail (surprise surprise) to which they have still not responded. (how convenient)

3 weeks later - I am stuck on 10/5 meg speed, and being held ransom as no other service provider can take over my fibre line without Vodacom releasing the line to the "holding pool" and providing the fiber B number.
