Client Service a FAT 0 out of 10 - pathetic

I booked a ticket for my son a month ago and miss spelt his name. When I made contact with Travel Start they sent me the number for Kenya Airways and said I must do it through them. The number they gave me was wrong and eventually I went on social media to get a response which I did. As my son is traveling with both Kenya airways and Air Dubai they can not make the change. They said it has to be done through the travel agent we booked through as they need to include a code for the change to be made. Today in total I have spent 40 minutes on the phone once it is my turn to be assisted the phone is picked up and put down. When I call the cell number the call is declined. Please call +***1 before I go on social media
