Poor customers services never get back to you

Hi
Had our system installed early December absolute joke. Messed around for nearly a week . Lack of communication from the installation manager and the helpline. Damaged my electrics and made my roof leak. I was informed that I would be given a £100 for the hassle back verbally from him and the roof fixed asap, nothing happened. Had the roof fixed and have paid a bill for over £200 for damage to the lead work. Still waiting for somebody from the 0800 number to get back. Going to an ombudsman to get these issues sorted. I have rung and rung with nothing in return. Stay away from this company simply fob you off and hope you will go away
