Over charged me and refuses to refund - Poor Service

Complaint - #***1 - I placed an order with Mr D yesterday, my entire order was a disaster. Mc Donalds could not supply all the items and the bill for McDonalds came to R140.00 but Mr D charged me R269.87. I logged a complaint and supp**** Mr D with all the information and photos as evidence. Mr D then persisted to send me the same worded response, from numerous representatives stating the exact same thing. Every time I rep**** and supp**** them with information, they would just send me the same generic response. I am not sure if they feel that their clients and service is a huge joke but over charging me, not ensuring that my order was correct and then saying they are going to give me a stupid coupon for the undelivered items is some type of compensation for getting their client's so irritated, is some kind of joke. I have never experience such a low standard of professionalism and clearly Mr D has no consideration for it's clients. The staff do not read the email trail before responding which shows incompetence and inconsideration/complete disrespect for their clients. I asked numerous times for a number so that I could phone them instead of having to deal with the annoying emails but nothing - they literally just sent me the same generic response - SO ANNOYING
