Misleading website

I've purchased the ms650 knowing that i can upgrade by adding the swa-w700/xa to the soundbar. Now it's nowhere available. Its really unprofessional and misleading especially since I've called the dealership that you've listed and said they have not had that subwoofer for almost over a year and can't even order one. I've got;

S9+ Galaxy smart watch Ms650 sound bar 49nu7100

In the past I've had S7 edge F5500k

I'm a really loyal customer
