Vodacom FTTH-The worst ever service waiting for 5 months to resolve a simple issue

Vodacom FTTH-The worst ever service waiting for 5 months to resolve a simple issue.i had raised request to include the VAT number of my company in invoice on 18th Feb 2021 and chasing for closure so many times and several escalations.After so many shouts,they confirmed it is resolved and they closed the ticket stating that this is updated and I would be getting the next invoice.Now it is not included and no proper response from anyone
