I have set up an alternative format with the DWP which means I now communicate with them via email re my PIP form. I asked for an extension and they granted it until the 10 May. Last Monday (17 March!) I got an email saying my PIP is being stopped because I didn't get my form in on time! I rang them and they apologised for the 'miscommunication' but said I won't get my PIP reinstated until they receive the form, this despite the money going into my account on Friday (21 March)!.
Despite the extension, I emailed the form to format.pip@dwp.gov.uk on Wednesday (19 March) at 6.40pm. No auto-acknowledgment by Friday, so I rang them again. They said they haven't received it! What I can't understand is why they sent my deadline extension from that email address and I could reply to that email to that email address?! Has anyone else experienced this lack of competence?!!
