Marbs parties/ Marbella adventures

I visited Marbella last Oct with a hen party of 40 people. We booked our transfers and pool party through marbs parties. Our pool party was supposed to be at secret gardens. We got an email the day before saying this was cancelled. We contacted marbs parties to get our £1,100 back that we paid. We got no response from them, we are now no further forward. Please be aware of these companies they are owned by matteus demetri he has many companies trading under demetri.
