Let's look at it differently;
You come to my shop and buy a packet of sugar and I tell you that it will cost you sh90. You pay and go away. Then I realise that I had undercharged you. Do I call you back and ask you to top up? No; I let you go and immediately up the price to the proper sh120.
15 minutes later you come back to buy more sugar. You have also realised that my price was much lower than the market average. Now; am I obliged to sell the second packet at the wrong price of sh90?
No,I explain to you that I had a mistake the first time round and that by selling at sh90 I am making losses.
Therefore; I wouldn't say 'KRA are thieves'; I think they realised they have been undercharging the duty on certain vehicles and rectified the situation.
