I notified both the ESA and the appropriate PIP Departments that i had a change of address... (ONLY) and no other circumstance's had changed at all.
This i had put in writing and as stated sent off via recorded delivery with tracking to the relevant departments.
I checked the tracking via royal mails website with the tracking number. and both the letters i had sent to them had been accepted and signed for by both PIP & ESA employees.
I asked them in writing to send me out in writing confirmation that they had received my letters of notification of a change of address only.
I still haven't had any correspondence back from them at all.
I did keep the receipts of postage & i also downloaded copies of the PIP & ESA employees signed signatures of receiving my letters. Just in case they try to come it as more often than not they do.
Question is should i worry about them not getting back in touch or should i ring them up asking why they have ignored my letters?
