No services from the bus company

Hi. Hope someone can help me. I booked and paid bus tickets on july. Then president put us in a lockdown so i had to put tickets on hold. Wat a struggle to get hold of someone. I almost used R200 worth of airtime. When someone finally pic up. The man was so rude and no patience at all and didnt help me. I had to call again. After sometime a lady pic up. She helped me and tickets was place on hold till i open new date to travel. The lady said its gonna be R50 on each return ticket. I agree. On Thursday i called and called. Same problem no one pic up. Finally when someone pic up i give my ticket numbers and ask to open new dates so we did moved dates. He say i must pay a R320 in his account in 24 hours. Why 320 from R50. Just before he give me the account number the line was cut off. I called again no answer. I send 2 emails and ask someone please call me they give me 24 hours to make a payment but didnt complete the explain on how to en account. I already paid in full R1900 the bus tickets. Nothing is out standing.Friday i called again no answer. I keep on sending emails no one response to it. I need to be on the bus on the date i give them. But no one come back to me to confirm or help me. What can i do. R1900 IS ALOT OF MONEY to wast and no service what so ever. They just ignore 6 emails from me.
