Bad After Care Service - ********* Conduct to protect poor workmanship!!

Rather use other companies, now I'm left with a mess after spending close to R18K. Bad after care service!!!! I did a solar geyser conversion on 27 June 2023. Immediately I started noticing that I do not get hot water the way I used to. I emailed Magnus at Solar Guru on 30 June after calling on 29 June about the problem. I was told its still winter and that the water would not heat up to certain degrees. The team came three times after the installation without any progress made. On the fourth visit to my house they told me I had a plumbing issue (water leak in the pipes) and need to call a plumber to check. I called a plumber and confirmed there is no leak. They refuse to fix their mess and claim I have a problem which did not exist prior to their installation. I suspect they send out inexperienced technicians that make a mess and are not able to fix it. I asked for the installation to be removed so that I can get my money back and they sent me a letter which says nothing but speculations about plumbing issues they cannot even verify.
