Has anyone else had this happen to them

Hi all,

The day before my esa to pip assessment interview was due i had a letter to say that it had been postponed,nothing to say why but what they did say was that they would write to me to tell me when it had been rearranged for.

Its now 5 weeks later and i still havent heard anything.

Im still getting my payments (which was a worry)..

Should i be concerned about this?

Has anyone ever had this happen to them and what happened?

Is there any reason why the assessment might have been postponed?

Kind regards
