All you can do is chase the DWP about the pension increase, did you send the letter using a Tracked post so that you have proof of delivery?
There are considerable delays in the ESA assessment process, some members have waited nine months or more but you don't need to worry about this, ESA is an indefinite award so if you are in the SG then your award will continue in payment until a new Decision is made.
