Bad aftersales service

I bought a Billabong bag on 17 April 2020 during lockdown. But a different bag was delivered on 9 June 2020, from the one they advertised. I've emailed them over 18 times already and I still haven't received any response from them. I sent them the link of what they advertised and photographs of what I received. It's almost 2 months now since delivery. They do not provide any contact number besides their customer service email address that sends you an automated email response back.
