Migrating from esa to uc appointee

I’m an appointee for someone… just last week became their appointee but the person only Monday had their migration letter sent to them..
1. Do I need to contact us helpline as she got letter and im the appointee
2. When doing the up claim does the email address be in appointee email
3. The phone number and address is this in claimants address or mine
4. The bank account … it’s going into mine as appointee but do I out claimants bank account details still as they should have mine on record as I already had one payment in esa last week
5. On her old esa letters at top it states the payment of employment and support allowance is based on national insurance contribution records and any additional amount the law says you need to live on (but figures below state your income related amount is £225.45 less total income of £0.00…… is she getting contribution based ? On migration letter it states you will soon stop getting the following benefits housing benefits and income related esa? What will happen
6 will I or she need to do a claimant commitment if I’m appointee?

Sorry for all the questions im new to this appointee stuff

So I called migration they did it over phone but now I had a text saying the person who’s claim it is has to go to job centre so I called them and they are saying they need to verify me as appointee but a visiting officer came on the 16 April, and I don’t live anywhere near the claimant. I have emailed mp… why have they got to verify me again as appointee when it’s been done only a month ago and went through for esa as I got letters and payments. Can you please help

Not sure if last message went through basically im appointee and migrated by phone yesterday they said I would get a call… got a text asking for claimant to go to meeting at job centre so I called up and they said it’s to verify appointee. But I already did that when visiting office came on 16 April. And I don’t live anywhere near claimant plus the UC asked for the claimants telephone number for which I said no because I’m appointee. I have contact mp but what can I do please

I don’t have journal as I did the migration over phone. Is there an email address I could sent to im in Suffolk
