Bad service

Goodday, I register a claim for a geyser on 04July 2024, on 20 July a new geyser was installed by 24fix as a service provider of Absa. I requested to keep my old geyser on which we agree, just to find out 2 days later when electrical has to be done that their service provider took the inside of my old geyser and left only the shell. What worries me is that the electrician that came out uo connect the geyser only the following day, wrote a report that the geyser installation was not compliant, it need straps and bond to secure it and they can only work on it if it's compliant. I contacted Absa and inform them about my situation and that the electrician will forward the report to them, the lady I phone ask me how can the electrician say that, they will send another electrician, who also did the connection although there was a report. I requested Absa to contact their service provider 24fix to return my geyser, without any success, I tried to contact them also no answer, what happened if repairs need to be done, how can I trust 24fix on my property as they took things without my permission? I went and read all reviews about this company 24fix and saw only bad reviews, how can Absa continue to use them as a service provider, do they take their customers serious? I reported all this to Absa and didn't get any feedback.
