Worst horror service

I'm writing this as a very disappointed and very angry customer ,with the service from air Botswana travel , I booked a flight and I cancelled within 24 hours I phoned I spoke to hlelani zondo to approve and I was told to send an email I got a confirmation that my refund and cancellation has been done and I will receive payment within 8 weeks , I received a call this morning and the deny agreeing to pay me back, now theh telling me that I booked via agents and they can't help me my concern is why I wasn't told this the time I phoned, or told on on time , so this could be sorted out they only contact me today , as much as they responded via email.. hldlani zondo was very rude and unhelpful I wonder if air botswana keeps people like that to work with customers , such behaviour is un acceptable and very disgusting I was expecting to be helped by all means possible as I am about to loose R2300.00 it's a lot of money and they phoned ,me to tell me they can't help me, I must contact the agents of which I dint hv all that information cause the booking was done online, the could hv escalated the matter were I can be helped, I never received such an attitude in my whole life.. I never felt so dis- respected isn't it they suppose to assist cause they managed to cancel the booking now going forward I cannot be assisted.i would like the matter to be sorted out and request my money back.
