Unprofessional customer services

This company customer services is not professional. I have made and order on the 25February 2022, made a payment of R160. I had sent emails, sms and chats regarding the microwave I ordered. Until had to sms asking, now it’s almost a month awaiting and I’m still waiting for their sms to receive my order. This is unprofessional regarding communication and assurance to their customers that my order will be delayed; until I contacted them. RENTOZA reply from sms that I could upgrade to another microwave with the payment difference of R60! How can I upgrade when I have not yet received my FIRST ORDER? Something about this company I do not Trust, I am hoping to receive my R160 deposit back. Very dissatisfied and disappointed with RENTOZA!
