Having suffered a cracked windscreen, I immediately contacted AutoWindscreens who are the designated screen repairers for my insurers (RAC). I was informed that the first available appointment was 2 weeks later. Reluctantly I accepted this and was given a time of between 9am and 1pm and was told that the technician would call me on the appointed date to give me a more accurate time. On the appointed date, I did receive a call but only to tell me that the technician had called in sick and a new date needed to be fixed. When I was told that this might involve a further 10 day delay, I insisted that this was totally unsatisfactory and, eventually, was offered a date 4 days later. The screen has now been replaced and, to be fair, the technician was most efficient and polite and did a good job. That said, I consider that 3 weeks is really not acceptable as a time to wait for a windscreen to be replaced.
