Advice please... on previous council tax exemption

owlgirllovestrees

Hello
Im new on here and I hope someone can give me some advice. 
After my husband checked his bank statement, our council tax bill has risen from £67 a month to a whooping £280 a month. This is for a property we own but do not live in 7 days/week. I think its classed as a '2nd home' and thats why the premium has increase. Even though I had a letter stating that from April the increase would be 100%, which would make it £134, not £280.
My quiry is our 'main property' is provided through my husbands job and on gov.uk this is on the exemption list. We provided his work contract stating he has to live there m-f for his job. We do not own the property. So our '2nd home' is the only property we own. Obviously I dont want to be breaking any laws, but its not a 2nd home. Its furnished and we do live it some of the time. I have emailed the council but had not reply. I dont know what to do. My husband is not sleeping because his worrying about the payments. 
Advice welcome, Thankyou

Something doesn't sound right. £67 pm is very low for CT. It equates to £800 pa, whereas basic Band A where I live (in southern half of England) is almost double this. What band is the house in and are you in England?

Did you not get a notice advising your total CT amount for the year?
