Fibre to the home - constant account problems

I have been with vodacom for almost 10 years, in the past year i have had numerous problems with my account to the point where i am now ready to part ways with them. I called in to have a price match done so i could stay with them on fibre services, this seems to be the worst thing i could have done,. Since then, i have had my account dropped from 250mbps to 75mbps and told it would be raised back up again only to find i have been billed for a 250mbps line when i only have a 75mbps line. This is now the second time i have to try and make this fix, only ifference is this time it cost me money. When i contact support its one department to another and i need to suffer because they make mistakes. Honestly in the last year i dont think it is viable to stay with vodacom as a provider.
