Misleading and disgusting service from Vodacom and Open Serve

My application for a fibre line was approved on the 4th of Jan 2021. I was then called by open serve and arranged a time and day for installation. I took the day off and waited. No show of them neither a call or message or even an email to say they not coming or reschedule of appointment. Whilst waiting for them to come I called Vodacom who then assured me they will be there by 1pm. No one got back to me since. I call everyday to get somewhere or some response. All I get is that its escalated and they will get back to me. I have the 3 Sr numbers and 3 escalations. I was promised by the consultant that Their manager Candice would call me to sort out matter. Still waiting. I explained that online school is commencing please can someone do something or tell me what is going on. All I get is that we will get back to you. Latest response yesterday was that I have cancelled my month to month contract hence installation was not done. I have written proof of all communications and no where have they got I confirmed cancellation. How do you guys keep misleading and mistreating your customers to a point like this. How do u go forward in this instance. No care for the customer, no service and certainly no compensation for the time and money spent on the calls, emails and frustration caused. Any suggestions from someone who knws wat I can do to remedy this situation. I'm so disappointed and frustrated in being let dwn and mislead by these service providers, it's a nightmare.
