I have been with O2 for five years as they always gave free O2 to O2 free calls-- I have just come out of hospital and no visitors allowed so we used our mobiles were unaware that this is no longer free calls --- I have come home from hospital and my wifes phoned has been blocked from being used until I pay £231.03 we have always paid our bill on time and never gone over the limit-- O2 never warned us that we running up a high bill-- we are 78yrs old and do not have that spare money out of state pension-- I spoke to O2 and explained what happened all I got was pay now or we send a debt collector and remove goods and the bill will double if that happens ---so think before 02 rip you off like they have myself
