Poor service from Vacation Management Service

I booked my 2021 December holiday in March 2020 at Dikhololo. Dates changed and my two week holiday is now split in to two different timeslots. I phoned VMS to try and move the two weeks back to back again. But was told I am rude and they don't need to speak to me, after which the lady from VMS terminated the call abruptly. The lady did not listen to my problem as I tried to explained what happened she kept on interrupting me before I was finished.

VMS can only answer specific problems and don't really care about the client whom they are suppose to help
