It is only possible to cancel in written.
As date of cancelation the date of receivement will count. When one cancels more than 8 weeks prior to the start of a training € 35,00 will be charged. Between 8 and 3 weeks this will be 50%. If a participant cancels later than 3 weeks prior to the start of the training no refund can be made.
However, it is possible to let a colleague replace you, in consultation with Dialexis Advies.
