Bad service

I made a booking for 6 people via eDreams and I realised there was a name error on one of the passenger's name I then reached out to eDreams to help me correct the error they directed me to Fastjet airlines as they claimed they could not correct the error, I then reached out to fastjet and asked if it was possible to correct a name error they said they do correct up to 3 letters in my case I only needed to correct only 1 letter but still am not getting any help from them I being taken from pillar to post.
