Poor customer service

I have sent at least 15 emails to Bright Swimwear and got no reply, just ignoring my problem. I have sent messages on Instagram which also has been ignored. I ordered my bikini last year in July and still waiting for it a year later. It was more than R600 that I payed. No one replies my emails on a refund or even delivering my bikini. Really dissapointed with this service. This is my last resort, absolutely useless customer care.
