COMPLAINT - PETS JEWELS SA

I purchased earrings from Pets Jewels SA ,online, on the 28 April 2020.Shortly thereafter I received a confirmation email from them of the purchase, the order number and a contact email address for queries. Nearly 3 weeks later I have had no contact from them whatsoever , and whilst I appreciate the difficulty with lockdown & that perhaps deliveries are delayed , I would have liked some response to my email queries. I emailed them on the 12 May & the 15 May to the email address supplied info@petsjewels .co.za & also visited their website and contacted them form there.To date I still have had absolutely no response from them!I cannot find them on facebook , only the same company in the UK.I sent the UK store a message on messenger and they have no contact details for SA???They assure me the company is legit & not a scam . How do I know this if no one is available to answer my emails/queries? I would appreciate any response.
