This company is unprofessional, unreliable and negligent! Over the course of 1 month I had to have 3 windscreen replacements due to their unprofessional service and inadequate windscreens. The first windscreen replacement had 3 big scratches down the drivers side despite being fitted on site at national windscreens slough, the second windscreen was not the correct model or specifications for my car (which was backed up In a written document by Mercedes) which resulted in my sensor on my car not working meaning my windscreen wipers and lights did not fully function for weeks. In fact they malfunctioned and left me stranded on the M25 but the regional manager didn’t care and offered me no apology or compensation. In fact the whole 3 windscreen replacements exceeded 8 hours of my own personal time for appointments again with no apology or compensation.
