Incorrect billing and poor service

Last year June I purchased a Mango airline ticket with my Edgars account to fly to Cape Town to finalise my wedding. I received confirmation that it had been processed and charged to my card. Imagine my surprise when I arrived a few months later at the airport and was denied boarding because Edgars had not paid Mango for my ticket. I then had to purchase a ticket in with British Airways costing R3200.00 because the flight that I was supposed to be on was the last flight for the day. I then called the Call Centre and spoke to Sandile Mabaso who guaranteed he would assist and get to the bottom of it in order to rectify. I mailed him on numerous occasions and have tried to contact him telephonically and guess what... no response at all!<br> <br> Now its March 2016 and Edgars has the audacity to send me a message telling me they never billed me for the airline ticket last year and they are now going to add it to my account. Are you joking?<br> <br> I would like to know how you are going to resolve this.
