OP yes my experience is quite different.
We love our Oyster cards and I've always been impressed with the speed and efficiency of their response. My DCs use it to get to school everyday and my DH commutes into town with it. I have pay as you go and use it a lot. When I've phoned the helpline (did it last week) I've got through quickly but I usually deal with issues online. I do however live in a totally different area of London to you so don't have problems with DLR for example.
Sorry about the "If it's not worth queuing for registered post for a tenner then it shouldn't matter if the card gets lost in the post as you're no worse off and possibly £10 better off". Didn't express myself very well.
What I meant was, if you give up, write off the £10 and decide to do nothing because the registered post is too much hassle (which I can understand) then you have lost your £10. So by using ordinary post you are no worse off than if you decided to do nothing and possibly better off (although still neutral with your original position).
I don't understand what you have been told about being charged for your journey information (which does seem like a rip off) as this is freely available online. All our cards are registered with TfL so at any point I can look up online and print off details of all my journeys (and the rest of the family) for the last 8 weeks.
monkeyflippers you can register pay as you go cards. All ours are and we manage all payments etc online. if you are due refunds they are then sent directly to your card. You can even transfer balances from card to card (although sadly not child or 16-17 cards, just adult ones)
mrskbpw my card stopped working whilst I was in Paddington last week. The TfL man at the barriers directed me to the ticket office. On examination they saw that my card had a crack in it (it's quite an old one as we have used Oyster from the beginning). Anyway, 5 minutes later I had a new card, balance transferred from my old card, job done, no cost to me.
All I had to do then was go online and update my autotopup instructions (where anytime the balance on my card drops below £8 it is automatically topped up with £40 from my credit card) to say which credit card I wanted the money to come from for the new card. The card details were already there when I logged on having been added automatically when they changed the card at Paddington. I was even given £3 credit for setting the new auto topup up on line.
Hmm, starting to sound as if I'm employed by LTR. I'm not but am interested by the problems so many people have experienced as our experience has been almost universally good. We've obviously been lucky :)
