Bad customer service

On the 26th of June I booked 4 return tickets from Welkom to Durban Friday 9th July. We were scheduled to return to Welkom on Friday 16th July.Unrest started to break out in Durban and on Monday 12 th July I sent an email to the company asking for a possible earlier return home. I did not receive any response.I called the offices on Tuesday morning and was advised that there will only be a bus back to Welkom on Wednesday 14th and that I should call on Wednesday. I sent an email again on Wednesday and was advised by Roxanne Snyman that there is no such thing .I called the offices and was advised that there is now a bus for the next day and was booked on that bus.A few minutes later I got a sms that bus was cancelled. I called offices on Wednesday and was assisted by a rude lady that said Intercape cancelled trip and that I will be given a voucher as refund to use in the next 3 years.I told the lady that I cannot accept the vouchers as refund as I need the money to get back home whereby she told me that I should have read the terms and conditions which I did and nowhere was it stated that a customer must take a voucher as cash refund.I was then rebooked for a supposed trip on Thursday which I also got an cancelation sms .I called offices again and was taken back and forth and later given an email for customer care who also insisted on the voucher story.As much as I understand that Intercape was within their rights to cancel trip I am also within my rights to get my money for return trip back as I will never ever use them again.i want them to refund my money to the same account that booking was done from .There was nothing on terms and conditions about vouchers as refund.
