Absolute & utterly disgusting service received from Vodacom thus far

If use the word 'appalled', I would be doing injustice & actually giving Vodacom (Fibre) too much credit, such is their absolute & utterly disgusting service (if we can call it that!). I am currently changing my package from ADSL to Fibre & I was asked by Vodacom to book online via the link they provided me, which I did as requested. The installation date & time was set for 28th OCTOBER 2021 @ 13h00. Today is the 17th DECEMBER 2021 and the fibre installation has still not been done. I have since the 29th OCTOBER 2021 continuously followed up with Vodacom through countless number of telephone calls to their Call Centre but met with little or no success. Every time I call them (Vodacom), they validate my details & state that the matter has been escalated. Eventually, a month & a half down the line, another installation date was set-up for a few days ago i.e. 15th December 2021 @ 09h00. A representative from Vodacom did arrived at me residence @ 09h00 on the 15th December. He asked me a few questions and then said he needs to do a quick survey of my property, which a agreed to. This guy then walked around my property and, after a few minutes, got into his vehicle and left, without saying a word and neither he or anyone else from Vodacom have ever been to my residence since. Needless to say, and I’m not surprised, that absolutely nothing has been done to date, in spite of my follow-up calls to Vodacom, who gave me the same old same old story, ‘the matter has been escalated’. Regrettably, I am stuck with Vodacom as they are the only service provider doing fibre in my area. If there were other service providers servicing my area, I would most definitely cancel my contract with this totally & utterly useless company viz. Vodacom & moved over to my new service provider of my choice. It’s now the 17th December 2021 and I’m still waiting! I need urgent intervention & assistance please!
