The best idea PR guys from PayU might have:
Dear Sir or Madam,
We would like to apologize for the INCORRECT INFORMATION in our last communication.
During the break which will take place on 27 November 2014 from 05:00 am to 05:30 am you could not be able to log in into the system but all transactions WILL BE SETTLED. A message informing about unavailability of the service may be displayed during login attempt.
We are very sorry for the inconvenience and misrepresentation.
Kind regards, PayU Team The funny thing is that I haven't got any e-mail on the technical break in the first place.
