Terrible billing, useless service

Quite a useless service with terrible billing and customer service. I called in Watergate to pinpoint the area of water loss in my pool as I knew there was a leak. I told them clearly I could see by the drop in water levels that the pool was leaking. I spoke to Justin about escalating charges before I confirmed the job. Very soon after the inspection all I received was another bill with an extra hour of work and more gas charge. I rep**** telling them I could confirm via my cctv that they were not at my home for more than 1 hour and received a response that it was just a mistake. I asked for proof of gas usage and have been told they are now using a method to verify the quantity of gas because they didn’t have one before me. The report was useless because all it confirmed was a leak I already knew with no solution of remedy besides the obvious which is seal the leak
