Poor after sale service

All started out good when booking through Travelstart. Until you run into problems . I have been emailing them twice. The first email I must admit could have been to the incorrect mail address. The second was read and today its been two days since its been read and STILL I have no reply onto my querie wrt the fact that my booking on Mango was paid for eticket received with no ticker number? As this is the first time I book online with them, I think even if there is not supposed to be a ticket number, I should be put at ease with my query instead of just left hanging. Although the booking I did the same day for return flights had ticket numbers???
