NEW eBill problem - could use ideas to correct

Bob.

I cannot recall why, but when I originally set up T-moble as an online biller which is paid by EFT, I had to choose a fictitious bank account to get the eBill to work. When the bill came in, I had to edit the instance to show the correct bank account paying the EFT.

Today I decided to change all instances to the real account the EFT comes from, and it unlinked the biller. Nothing I try can relink, even going back to the fictitious account.

Either, trying to link creates a NEW eBill or it tells me no eBill can be found on the existing.

This worked for years with a fictitious bank selected under "account". Right now, if I cannot get correct, would welcome that back.

What can I do to correct this?

Thanks.

Bob.

Well, one thing I did not try was to create a new biller. That seems to have worked though it shows my last payment as maybe 10 moths ago and now awaiting the "first" bill. I deleted the old series that was no longer linked. So hopefully this will work without issue. I will not know for a month.
