Just my two pence worth
Last time I used the DVLA to tax online , and used a debit card , went to the bank the next day and was told I had no funds in my account
Long story short, when checking statements with the bank , 2 seconds after the DVLA payment was completed there was a transaction for £1, followed by, over the next 2 hours, £4000 of online shopping.Fraud investigator at the bank said the £1 transaction is a test made by the scammers to check the details theyve just hacked will work.
So it might just be me but any hiccups with the DVLA web and id be out of there quick as fuck and have always taxed at the PO since
DVLA did not respond at all to questions I asked
So if your mate wants to carry on with it use a credit not debit card
