GoSolr - Worst experience ever! Empty promises

GoSolr has been nothing short of diabolical. We had system installed approx 2 years ago. We had endless issues with remote ****les that were changed and changed - the app hardly ever worked. Even though their technicians came out several times, not one of them identified that our DB board had been incorrectly wired from the day they installed the system. it was in fact wired unprofessionally and does not confirm with the regulations and standards. We have now sold our house and because of the COC not been issues due to the bad installation, the buyers won't even look at GoSolr as a supplier and they are also not interested in taking over the agreement. Despite numerous requests for somebody senior to contact me, GoSolr has failed to get back to us and because of their poor service the transfer of my house is on hold which is going to incur penalties and so we have also asked them on numerous occasions to come and take out their system to which we have also had no resolution. Apologies and empty promises is all I have been give by the person whose name is "Hope". we now find ourselves in a massive predicament and still no service or resolution. I even sent their senior engineer a message and no response. @gosolr please just come and remove your system so we can get on with our lives!!!!
