Been asked to attend job centre while in support group.

Hi. Could anybody advise me of what to do here.
I completed the managed migration of I ESA to UC
after recieving my letter in the post last week.

After completing the on line migration i was informed
i wuld recieve a telephone call in 2-3 days.

Now i have a message in my to do list that i have to
attend a Job Centre appontment tommorow afternoon.

I am transfering from the support group ESA to UC.

Is this a mistake on the DWP after telling me they would call me.

Thank You for any advice.
