I booked a holiday for 6 people with tropical collection leaving from London Heathrow to Bangkok. When completing the booking the representative Laura discuss the external flights with me as well as the hotels. I agreed with what she told me and said she can go ahead to book the flight. When I checked on my computer later I saw the confirmations come through and realised that we did not discuss internal flights. When I emailed to ask Laura about the internal flights she did not call me back. I was then busy on another line and didn't check my emails again till the next day. When I checked my emails I saw that she had booked my internal flights as well, however without my consent and I was not happy with the times that she had chosen. I called the company and spent 30 on hold before someone answered only to be told that they will need to look into this and will get back to me within 24 to 48 hrs. I then had to call them as 3 days had gone by just to find out by another representative that no one has bothered to looking into this. The representative then took all my details again for the second time and again told me that she will have to find out. After making 7 to 8 calls to them each time I had to be on hold for at least 30 mins I was told they need to speak to Laura and she not there etc. When I was informed that the change will happen on Monday the 2^nd Feb when Laura is at work, however due to me being at work I asked her to update another friend who was also booked on this holiday. She then called on Tuesday after no response and was told that this department does not deal with this issue and that she needs to go back to Laura and when she spoke to Laura that day she was told no she needs to speak to customer services. When she asked to speak to a manager she was informed that the manager is happy with the service they provide and that I was given 30 mins to called to change the flight information if I was not happy and the no contact was taken as its fine. I did not authorise this payment and they have taken all funds out of my card. They refuse the make a full refund and refuse to change the flight time. This transaction was illegally complete with my credit card without my consent and when I contacted them to inform them about it no one has taken responsibility of this least of all the managers who refuse to speak to us. I want to know what I can do to get the flight information changed and refuse to pay for any changes.
