Hello

Recently i joined the course MCDST,MCSA+M with microsoft Gold certified partner ,for 1000 pounds .i have some issues with training provider,so next day i went them to cancel the training ,they replied we registered you with microsoft & we paid 2000 pounds for this training to microsoft .so we cant cancel the course
Does anyone know if somone booked for the training with the training provider,Does they have to pay for every single one who registered with them ?
