I had left my lights on and drained my battery so called RAC. The patrol man was rude to me saying it was "my fault" ...I know it was but these things happen and I was shocked that he was so rude, after all I didn't do it intentionally! He told me that because I'd left my lights on I'd damaged my battery and would need to replace it. He put it on charge for 15mins then told me it had failed the test. However I was suspicious and said no, I would not buy a new battery as mine was only a few months old - I've been driving nearly 40 years and have had flat batteries before in the past and just had a jump start with no further problems. I went back indoors after thinking he had finished, then 10 mins later he was still on my drive and rang me on my mobile asking me to go back outside and offered me 40% discount on a new battery. I once again said no ...I felt very uncomfortable to be honest. I then did a Google search after he'd gone and found that Watchdog had done a report on RAC a few years ago for getting people to buy a new battery when it wasn't necessary. Looks like they are still trying to do this!! My car is now running fine after taking it for a nice long drive straight after.
