Hi had a letter to say tax credits would ring for a telephone compliance interview, they didn't 🙄. I'm having trouble trying to call them to find out the next steps. Main phone number gave me another, but didn't have an extension number on my letter so had to wait in line, that went back to the main line 🙄. Was told then to put 02 for extension that just rang for ever and went back to the main line🙄. Anyone have any numbers please for said department tia
