I can't comment on their ability to replace windscreens as they apparently failed to allocate someone to my job, I found this out after waiting for 5 hours for them to turn up in the 8-1pm slot I had booked. Their response to this (and I'd waited 2 weeks for the appointment) was that they'd need to reschedule a new appointment at the next available slot, there was no urgency from their perspective, no, I'll see if we can get someone round today/urgently as we'd made a mistake... nothing bar a slightly lame "sorry". Then they couldn't tell me when the next slot would be as their system was down, so they said they would escalated the call to the local branch, when I asked how long it would be until I heard from them the response was "I don't know, it depends on how busy they are" over 24 hours later, their 365, 24x7 service has failed to call me and I'm guessing I won't hear from them either. Time for me to call my insurance company and see if I can get another company to complete the job as these guys have no concept of customer service.
