I needed to telephone PIP to increase the time for my form to be returned. After spending 35 minutes going through god knows how many prompts it gave me a different number to call than the one on the form.
Went through it all again, only to be given another number.
Finally after being on hold for 40 mins I got to speak to a human!
So just to share this number with you all, as it will no doubt save you some precious time. It is.... 0800 121 4433
Not sure if different numbers are given out for each region you may be in. I'm in SE England
