Hello. I bought an S23 last August and it came with a free Galaxy Buds 2. Recently the right bud was not working or connecting. Weirdly, it is still charging and drains the case. I already tried resetting the buds. I contacted the store I bought it from (not an official Samsung store, they sold it cheaper and came with more freebies). They told me it is not covered by any warranty. Is this usually the case?
