How do i get my $4000 deposit back fro Capital Auto Group in Vaudreil

I put a deposit down of $4000 at Capital Auto group between 09.05-
09.06.2024
for a 2014 BmW X1 .On oct 1st due to a family member having a stroke and
no longer able to work i asked for my deposit back.They said accounting will
look after it  It has been 3 weeks and no one will call me back.On oct 18 I
spoke with Akram a sales person he said accounting had processed
payment and should have it any day.A week later no depost received.No
one from accounting called.No one returning my calls,emails or texts.I have
never been treated so poorly in my life.I would't want to be associated with
them if i were Car Gurus.Is someone able to contact them to address their
unbelievable service.Also they have sold the car that deposit was put on.So
they have my $4000 plus a payment in full on the same car.I have tried
everything.Soory for the long message.I hope someone can do something
