Irresponsible,and bad service

Wrote email on 9 Jan requesting to reschedule my booking due to a family bereavement, todate no positive response, series of communication is as follows: 11 Jan, ref*** & ***; Debbie response on 20 Jan asks for booking confirmation, ref*** and never comes back to me. Sibusiso responds on 26 Jan, ref*** and never comes back to me again. I wrote again on 4 Feb and automatic response ref*** and case ref no***. Still waiting for them to confirm the new booking details after rescheduling my booking. Cape Town will be full for the weekend I have asked for and I will not take any excuses as I have been talking to them for a month now with no positive feedback. I submitted death certificate as proof for rescheduling and hotel booking confirmation as requested. this is very irresponsible of you, very disappointing.
