awful service

Appalling and unbelievable service. I have made an online flight booking on Air Botswana last night and have sent the PoP to the designated email. I have been trying to call them the entire day, specifially the jnb sales contact number but no one is picking up and I am not getting any response to the emails I have sent to bookings as well as jnb sales. what I find interesting is the fact that my booking will lapse this evening because their 24hour period has passed but I have done all i can to have the payment allocated accordingly. I would not recommend using them at all.
