Inconvenienced by Travel agent

My husband and I went to Thailand for a holiday which we booked through Imagines Travel holidays. Donna Blackwell assured us that our holiday was going to be a great experience and had handled all of our booking. She mentioned we could contact her at anytime and she would be of service. It was our first time out of South Africa. We had a disastrous start to what was assumed to be a well-planned and paid for vacation. It was our first holiday abroad. Imagine Travel has put us in undue expenses because of their incompetence in this booking. We were also denied the opportunity of doing all the activities/tours that we planned for and going shopping on our holiday due to unforeseen expenses. It really put a dent in our pockets. We had already paid for our holiday, accommodation including breakfasts and air tickets. The last thing we expected to do was to be forking out money for alternate accommodations. We have been in contact with the customer services of Imagine Travel. All photos, receipts and communication have been filed and were emailed to customer services however the most they can offer us as compensation is R1500.00. It is an unfair compensation because we had spent alot more
