Totally shocking service

Payed my last installment to them on the 29th April and today 30 06 2015 I still get a statement from them after contacting them twice requesting that the account be closed, the account is still open .. and today again .. I get the same story from a line manager that I got from the previous 2 consultants stating that they will mail me and close the account ... will it happen ... ??? <br> <br> I just really dislike dealing with them, some how they managed to change my details on their account .. no one has bothered to fix it and change it back to the correct details, so my initials reflect an I .. instead of an N... really .. after how many calls do I need to ask them to change it .. or will they just keep it like that .. I will eventually be the one who will reflect a bad name for this not them .. but they are *********** and give the worse service ever !!! <br> <br> I absolutely hate dealing with them !!!
