Aerialforce provided an excellent service when providing an estimate and carrying out the work. There aftercare and customer service is disgraceful. A day after the work was carried, 3 screws came lose and fell out from the back of the TV bracket. I contacted them ASAP, they were unable to book me an appointment for an engineer to come out straightaway. They gave me several dates for one when someone would come out, no one has turned up since ! I received a phone call from the engineer that carried out the work, he told me that we had moved the too much, forcing the screws out. So without even diagnosing the actual cause , he has just assumed this is the problem. He told me to put the screws back in. I informed him that I paid a considerable amount of money for the TV to be mounted onto the wall, therefore I was no going to fix his faulty installation, making the guarantee void. The engineer has also lied saying the customer had put the screws back and the TV is now fine. I would suggest you go ELSEWHERE , do not use this company. They say and do all the right things to have your business and once payment has been received, they do not care about the aftercare and your customer rights as per the guarantee.
