Consultants incompetence costing me financially!!!

I made a booking with Cara Lurie for myself and my daughter for the Mothers Day weekend (12- 15 May 2017) for Victoria Falls. However 10 days prior to the trip i asked that my trip be rescheduled to a later date since my daughter had found out she was pregnant and was advised by her gynecologist not to travel due to malaria risks she could be exposed to. I explained these reasons to the consultant and she advised that the trip can only be rescheduled to a date that is within six months.

I then decided on the dates 22- 25 September 2017 and informed her of the changes on 11 May 2017 and awaited her response for confirmation. She then advised that she would be in contact with the Hotel and airline to find out on availability for the new provided dates. After much waiting and calls made to follow up, i received feedback on the available dates only on 3 August 2017. Much to my surprise the penalty of the flights and accommodation being the actual price of the trip itself. What annoys me is this that i gave the consultant sufficient time to make changes and confirm booking since i had long paid the full amount due. I am very disappointed with the service received as this is totally unacceptable and has cost me financially.
