Just placed an order there (Farnell) for the first time in ages, usually use RS, I have accounts at both.
Order seemed to progress normally, around £10.
At checkout NO delivery or handling charge was shown and I authorized the payment on my credit card.
When the invoice arrived by Email today a £3.95 handling charge had been added and the total amount charged to my card increased accordingly.
As far as I am concerned that is an unauthorized transaction, I have already reported this to Farnell's complaints system and if there is no response in the next few days will take it up with my CC company as a disputed transaction.
I don't care what there T&C's say they cannot charge the card for more than was shown at the time of authorization, I should imagine the distance selling regulations etc come in to play here as it is clearly fraudulent and misleading behavior.
