Is UBL online working for you?

My latest two transactions appear to have been "rejected" for no apparent reason.

Is it some glitch in their system or is it just me facing the problem?

It has happened with me sometimes. Once I had to wait for 24 hours and re-do the transaction and for the 2nd time, it went through successful after like 5 minutes. =) Call their toll free number, 0800-11825 just in case it does not go through for you again.

If your Local UBL branch is down then you will face transaction rejected error ....

its happend to me quite often

It worked after an hour. I think my local branch was down as Kamran pointed out.
