Affirm Loans review: loan application for phone

In 2017 I purchased a new phone for my son and was approved to make monthly payments on it through the affirm loan company. The phone was near 1000.00 total and I made the payments and in the end finally just paid it off early. No problems and fulfilled the agreement 100%. Several months later I needed a phone myself so went to use affirm again as I figured since I used them before would have no prob using them again. After I got my order selection and was setting up my payment option, I chose affirm like before and they now suddenly won't offer me the payment plan again or this time and they have no reason not to its all same info and I paid off last one early so, I tried several times and get same thing and am told unable to confirm identity yet I had same info before and got it no problem... Nothing is different and it's very frustrating. I just want to get a new phone and had credit amount approve before I found phone and then suddenly it said I wasn't any longer... Th
