***** on account and reversals not done as promise

At the end of August 2015 I received a letter in the post from JET stating my account is in arrears. i called immediately on a Saturday and was told it was mobile content. I have always been in credit with my account and apparently someone had activated some mobile content. I assured them that it was impossible and they needed to see who is committing ***** with my account. I have spoken to numerous staff and things was not getting sorted out. Eventually i spoke to a manager with the name PETER and it took over 3 weeks to get sorted out. I was assured it was done. I have asked for emails and letters, but only received one email from Peter. When i called about a week ago, they confirmed and RCS confirmed that the charges were being reversed and it would be corrected. Yet today I receive another letter, stating they communicated with me regards with the overdue account, which the DID NOT, i have been trying to get THEM to sort out. My name also MUST be REMOVED from ITC as this was all INCORRECTLY loaded on my account and i am not responsible for THEIR *********** staff !!! I WANT A LETTER TO SORT THIS OUT IMMEDIATELY ! It is not MY job to do your work for you!!
