Carol Reaney says that many mothers missed out on Mother's Day cards because people like her inadvertently underpaid postage (Oxford Mail, March 11).

The same happened to me.

I sent the Post Office five second-class stamps. The card was delivered two days later.

I quite agree with Mrs Reaney - the Post Office could have sent it second class.

It would have arrived late, but it would have saved a lot of aggro.

They say use the post office or lose it. I don't think much of their service.
