Instead of waiting to reinstate (I have not tried to do so) - Just open another a/c with new email add. Why was your a/c suspended?
If you need to do business everyday, open another one immediately. At the same time, contact Google to ask why and ask them to reinstate your account (it is worthy if the quality score of your keywords is high).
Thanks for your replies. Google said that they suspended my account because I had not complied with their terms of service and policies. I did write to ask them about it, they were not specific as to what I did wrong, but I think it is because I used too much capitalisation in one of my ads ie FREE and I used the word "best" one time. Oh well, my mistake and you live and you learn. They also said that suspension is indefinite. Since then I have searched on the Google forum and others have said that Google is very strict, once you're blacklisted, you're blacklisted for life. Have thought about opening another account, but somehow afraid that they will know and be able to track it.
