No human voice at Karibaa

Order Number ***: We ordered a product on 20 September 2020. We were asked to send through proof of payment and we did so twice. David responded confirming receipt of the proof of payment after which he wrote another one asking for proof of payment. Another e mail has just arrived on 29 September asking for proof of payment and again that was resent. Is David a Robot? All attempts to have voice contact with the company are futile. Is this contrived inefficiency or there is something we need to do. Is there an option to collect stuff? Does this company consider customers at all? Does this David really exist?
