Pathetic service from TravelStart

I booked and paid for flights on the 16th of March which was successful, only for them to debit the flights again on the 24th of March. After sending over 10 emails being on phone calls longer than 15 minutes each where nothing came about I sit 4 days later with my account being on hold and Travel starts pathetic service to send an authorisation letter to Capitec as requested on Friday the 24th of March. as I stated to Travel start when i initially requested the letter it is the only bank account I have, I STILL SIT WITH THE PROBLEM NOT RESOLVED and the staff at the call centres living their best lives leaving me on hold for OVER 10 minutes each call!!!!!!
