Incapable of fixing your own error

Two months ago I upgraded my ADSL speed and you created a whole new account for me in error. Today my line has been suspended because of this. I've called your useless 10210 number and even lodged disputes which were rejected a month ago. So you are declining to fix your error!!! Are you serious???You must seriously have a ego problem or you are delusional . I've spent a lot of time explaining to your call center what YOU did incorrectly. I had to purchase mobile data to keep working and I've spent hours on the phone. I will bill you for my time and for the data I had to purchase because of YOUR error! You are incapable of correcting this!!!!
