Contigo Energia Gesternova

On the 9th of September 2022, Contigo Energia installed a four-panel solar system. During the installation, they damaged my roof, which resulted in my bedroom being flooded with rainwater, over a three-day period.During the installation, the technician who fitted the electrical installation, wired up the system incorrectly. The installation was also wired into the main energy grid in a way that meant the meter read my solar energy production as consumption. This meant that over a six-week period, my energy bill to EDP (who supply my non-solar energy) increased by a considerable amount.Throughout the last six months, I have communicated with Contigo Energia via email and I have copies of all of my correspondence.When I initially informed the company that my roof was leaking, it took them two weeks before they came to repair the tiles they had damaged. It took another two weeks before they came and correctly wired up the solar system.The rain water damaged my bed and stopped me being able to use my bedroom for three days. Due to this and to the increase in my electricity cost for the first six weeks, I asked Contigo Energy to offer me a reduction in my final invoice, as a way of compensating me for the inconvenience, damage to my property, and increase in my bill.To date, they keep ignoring my request for compensation and keep telling me that mistakes happen and telling me that my system is now working.They took 4 months to respond to my first email, which outlined the issues I had experienced. Since I received that response, I have written to them again, stating that they have not addressed the different issues in my email. In addition, I have also written to them telling them that all of my last six months' electricity bills (from EDP) have increased by a minimum of 20%. This is of great concern to me, as I would have expected my energy bills to have decreased, due to having four solar panels fitted.Their response to my increased bills, was to tell, I must be using more electricity than prior to the solar panel installation, which is not the case.I am at a complete loss as to what to do. I have still not paid their final bill, as I have been waiting for them to offer me a compensation reduction. I have also been waiting for them to explain to me why my bills have gone up rather than gone down. I asked them to contact me by phone, but they ignore my request. I would really appreciate some help to know what my legal rights are and if I have a case to ask for compensation and if I have a case to request a full inspection of the solar system to work out why it is not offering me any reduced bills.
