No customer service. No refunds!

I understand it’s lockdown and Zulzi must be overwhelmed but they do not respond to customer care emails, Whatsapp’s or Facebook direct messages. I have sent several messages over the past two weeks regarding refunds due to me and get no response. This is unacceptable. Zulzi owes me over R1500 in refunds for goods ordered and paid for, but not delivered. They are reflected on the app but not paid back to my credit card. These orders go back to 27 March. It’s totally unacceptable to not refund money debited for goods unavailable! And also totally unacceptable to run a company with no customer service. I have seen numerous complaints on social media forums about Zulzi and the lack of customer service.
