carrers allowance and income related esa

I have real concern I inform esa that I was receiving an insurance from my employee to help with paying bills, I was sent to a medical and now they have placed me in support group I spoke to CAB and benefit adviser that because is was a wage my careers allowance would not be a affected and my insurance from work is not permanent. just wondered if any one else has had this problem every time I speak to esa I am told someone will contact me and I have been told I can not just turn up and the job centre without an appointment I did but security sent me away due to not having an appointment. 
please advise me I now it takes time but this has been 3 months now.
thank you for your help.
