Increase in holiday price after paying deposit

dizzzy

Hi

I'm after some advice regarding a holiday that I booked at the beginning of August for next year. I booked it on the internet with a reputable company which I have used before. I was given a price of £600 and paid a deposit which they have had since August. I received an invoice from them at the time with this price. I have however received another invoice from them this week and the price has increased to £1300. There is no explanation with this invoice stating why. I phoned them yesterday and was told that they hadn't added an accomodation upgrade supplement and that is why the price had increased.
They didn't have any supervisors in at the time and I've got to ring back and speak to them today. I just wanted to know before I ring were I stand. Can they just increase the price by more than 50%?
When you book through the internet it calculates the price for you. The only change in price they say might happen is the price for the ferry/eurotunnel. This is because they haven't had confirmed prices from those companies for next year yet.

Any advice would be appreciated, thanks

You mean over 100% increase!!

I would read through the terms and conditions of what you booked. Does it say you've already paid for this upgrade? Could you specify you don't want the upgrade?
