Short Response - then nothing.

Hi There,<br> <br> So I made a booking for Avis, nice and simple. Then I was told by a friend that if the return time is after the pickup time, you pay for an extra day. So My mistake. I acknowledge this. Not an issue.<br> <br> Now because my return time was an hour after my pick up time, I wanted to move the pickup time 30 mins later and drop the car off a half an hour earlier. This would then save me a day of fees and I had tested this on the website. I also do not mind waiting for a bit to collect the car or drop it off a bit earlier. I can - it's easy.<br> <br> Now the crux of this whole matter is a polite email was sent asking if I could shift the pickup and return times to avoid paying the extra day. The reply was \Please note that we work on 24 hour basis therefore reducing the rental by 30 min wont change anything\" and upon asking the agent to re-read my email re times, I now am not getting any replies at all. I am so disappointed with your service as a first time customer. Next time I'd rather go to another company, even if it is more expensive, ill pay for service.<br> <br> Your Motto is \"We Try Harder\"
