There is no point your sending letters to your local Jobcentre Plus office, they don't deal with Mandatory Reconsiderations, your letters should be sent to the Benefit Centre that deals with your claim.
I don't know whether the Chippenham office is covered by the Wolverhampton Mail Centre or not, but the DWP internal mail system is extraordinarily slow and it can easily take 10 days for a letter to be registered on their system.
It does somewhat make a mockery of the idea that MR's can be dealt with in a couple of weeks when it can take this long for a request to get to the right department.
