I unfortunately had a very large crack in my windscreen and went through my insurance to sort it out. To summarise, national Windscreens caused me so much unnecessary stress, time and annual leave wasted. For more detail: FIVE bookings cancelled by them which were- 1: got a text saying that my booking needs to be changed due to their website going faulty and the day I booked actually had no availability. 2: I received a call the day before a booking, and was told it needs to be rescheduled due to the technician injuring themselves, fair enough. 3. I kindly asked if I could be squeezed in a couple of days after the booking was cancelled, as the next availability was a few weeks away and the crack was getting worse each day. This was agreed by someone on live chat who claimed she spoke to the branch manager. The day before I was going to the branch, I received a text with a booking in a few weeks. I called to clarify, and stated I was coming in the next day as this was agreed by the manager. The girl on the phone was very confused and said i only had the booking in a few weeks, but she said she would speak to the manager to call me, in which I never received anything. 4. At this point I was losing my patience and complained, in which after speaking to a manager, she booked me in ASAP which I was grateful for. However, a couple of days before I received a call to say that my booking needs to be rescheduled due to the workers being on annual leave. 5. After rescheduling again, I get a call on the day to say that the windscreen that has come in is all scratched up and needs to be rescheduled, again (!!!) I was anticipating on the day after rescheduling that I would get a call, or nobody would turn up. Surprisingly, someone turned up and did a great job. Wow, what a process!! What was even more frustrating was that I received a digital letter stating along the lines of "we accept fault on this occasion" and only considered a couple of cancellations, not all 5! Their ignorance makes me wonder how they're still going. Please do not use this company, if I get another windscreen crack I will 100% go private than experience this again.
