Uber eats no delivery ,no food no refund ,customer a ****

Poor dishonest delivery service . Ordered KFC for R515 + tip of R51.50 Food was never delivered. Marack says he was at my house ,although they cannot confirm to me that he was at the address on my Uber profile .He says nobody answered the working doorbell ( 3 people were at home) He says he phoned me - my iphone records reveal no evidence of a missed call .They can not explain what they did wit the so called undelivered food .No visual proof of food left at my address . Food was never delivered and no account is given of what happened to the so called undelivered food of R 566.50 They refuse any refund ,calling me a **** .Mr Delivery will put a nail in their coffin Uber eats agent N Iqabal
