The phone call led me to a rude employee that made feel stupid at my enquiry and made a snide comment on my question about whether there is a centre that I can talk in person. I struggle with forms and phone calls as it is let alone being met with the disgusting behaviour from the employee!

You put my mind at ease immediately and for this I am very grateful as mother died and I have so much else to do other than worry about whether my return arrived or not ! So polite and so informative . A huge thumbs up to CARDIFF TAX OFFICE .
