Just ran my postcode out if interest and when looking at plan details it said 54mb average download but only 5mb average upload. Sure everyone will check when ordering themselves, but thought I'd mention.

Customer service almost as bad as Scottish Power or Talktalk but not quite!
Before you buy just check the Topcashback account to see if it has tracked to be sure i do it all the time now and always get a payout!
Good price even without cashback Vodaphone just put my 50mbps up to £21.86 after getting a deal for £20 for 24 months i thought it was fixed price didnt know they could up the price so beware folks sneaky these ISP's
