forced to pay over £500 to leave virgin

in july i am due to move to my sisters home as i have  leg problems and i contacted virgin to say im moving and i cannot take my services with me  due to the  fact its my sisters home,she  has sky and dont  want  virgin media.

after  a  few  calls to virgin media they will not  release me from my new  contract,im a  week past cool down,because if the  area i move to has  virgin media  i am expected to take  my  services with me,which i cannot do,and round in circles we go,last bill could be aas  much as £500 plus,which i cannot afford as i am on a  pension.its hard to beleave that i have been a  loyal customers for over 15 yearts and i cannot get virgin media to understand  i am not allowed to take virgin media with me,even asked i could get a  reduction on mylastbill,say half,but no virgin want there pound of flesh.so i will move in july and run up a  big bill,thanks virgin media for you  not  helping  a  good  customer , i did all i could to reason with vvvirgin media but they just wont  help me,they say they cannot help me and wont  budge,thanks for nothing.
