Not quickly, Sir:-)

It's the expected behaviour when one pays for a service. They don't expect hitches like these. Mine was such that some SMS were getting delivered while some were not. I tried to establish a pattern, whether it was prefix related, but it wasn't, so I decided to call CC (Customer Care), and was told the same: Switch off and on for a few minutes. It was hard to "buy" that as a solution so I just said my prayers and later it just worked.
Of course you had put an ad on the papers regarding the maintenance. The only problem with that as was it said you only expected it to affect prepaid customers.
I, being an Advantage customer, never expected to be affected, so I believe I (as an individual) am/was entitles to that assumption that you fear:-) It might be the same case with Adera, but I don't know.
