Next Credit. - PPI? Help!!

money_maker_mummy

Hi anyone can you help? back in 2009 I ordered some clothes online, from Next. When they sent them they sent them to my previous address (I forgot to change it). I got in touch with them and gave them my real address and they resent them to me - but to my old address again. Luckily i managed to get them from my old address as the tenants gave them ti me when i went down. The total spend was £260 ish. I got these for my son however most didn't fit him properly so i asked to return them. 3 times i requested a collection and 3 times no one came. I was 18 at the time and on income support as i was a lone parent. I tried to send back about £100 of the clothes but no one bothered to collect them. In the end they was demanding all £160 back and and it was passed on (i think) and i offered a settlement of £100. Could i have been charged for PPI? And what about the catalogue charges? i never asked for a catalogue as i could look online but got charged for it anyway. I've never bought from next since - and the worst thing is on my credit report its ruined it saying i owe £60 - when they agreed to the settlement of £100 - however they have not contacted me. Also I never signed an agreement or anything.
