purchases I felt I needed

I'm sorry but I feel that's a weak excuse.
Especially if you say you only want to quit now because you don't like their service.

I see this a lot with americans, they have little motivation or conviction.
The political situation is a good example.
They can barely get themselves to do a half-assed one day strike.
While in Europe we strike for days and burn the streets fif they even think about doing a fraction of the shit your regime does.
The No Kings BS, not buying from Wallmart for a day and other embarrassing and futile acts will not do anything.
You have a mentality problem.
And it's only going to get worse until you all grow a spine.
I wish you good luck (sorry if it sounds hard but it needs to be said)
