esa review

had to ring dwp in April re annual adjustment of a reduced esa benefit due to small increase in ex employer pension amount and official said i was due for a full review this June...and to 'just fill in the form when it comes' so I started to prepare in advance with guides. Not received anything yet but we have a week left of June...has anyone had their review extended further ...am a bit wary of calling them in July if nothing received by month end. Am aged 64 in July and in support group...was due in 2013 for review originally that was deferred till now. Having just posted my wifes DLA to PIP stuff after weeks of prep there is not much left of my aching brain! Maybe they should put a claim filing descriptor on the forms!
