Zen, about 50pm for land line, most phone calls (not to mobiles), FTTC
broadband with unlimited usage and a UK based helpline who talk English
and do actually help. Nominal download 76 Mbps but can hit 100+ hard
wired. Actual usage (teenager in house!) usually 5-600GB per month
downloaded, but has been over 1000GB without a word from Zen.
