It's a familiar situation, I've come across private traders who demand twice as much at the end of their work, motivating them with heavy boxes. Last time, I took a stricter approach to the issue and contacted a large legal company with a transparent evaluation system. Dispatchers from Paradise Moving & Storage immediately compiled a detailed list of the property, calculated the total cost and sent a confirmation by mail. The movers arrived on time, polite, tidy, no profanity or idle talk. They did the work quickly, without the deliberate time delays that occur with hourly pay. As a result, I paid exactly the amount that was initially announced, without a penny on top. I am very pleased with this service, because transparency in financial matters is now a rarity among transport companies. I recommend paying attention to large companies with clear rules of the game.
