Has anybody successfully done this recently? I tried to tax both my and my wife's car online today. I had both our V11's in front of me. I typed in my reference number only to find that it wouldn't accept it. I checked and did it again with the same result. Exactly the same with my wife's. I then tried to do it over the phone only to be informed that they were receiving a high number of calls, told goodbye and the line went dead. Decided to phone DVLA services only to find out that it cost £3-60 a minute. Disgusting! The whole system is shambolic.
