Perhaps if you can get written confirmation of a deal like Infinity working within 1 week of current order day, or I have ADSL2+ free until Infinity arrives and Infinity 1 Unlimited at £10 per month once it goes live (i.e. about their best pricing) then move, otherwise if it was me would be staying where I am, unless that provider is also having congestion issues.
