Hi Wat,
Sorry to hear this!
I'm really pleased to hear you've happy with the service you've required up until now, but it's always disappointing to hear when that opinion is changed.
If you'll give me the chance to look at this I'd really appreciate it if you could drop me a PM with your details so I can trace the policy and ensure we're doing the best we can, it seems strange that the price would jump so high without a reason.
I look forward to hearing from you soon.
Kind regards
Dan.
