Absolutely Poor Service

This is not the first time we make use of City to City and about every single time they late. Never on time. My sister needed to go back home from Midrand to Kimberley yesterday. When I booked her ticket they asked me for her number and emergency number which I gave them. Yesterday her bus was supposed to leave at 12:05 from Midrand. We have waited until 16:00 for the bus. We have asked around and only to find out from other bus companies that City to City is on strike. No SMS. No telephone call. No whats-up. We then had to book with Greyhound to that she could get home. They only could help us this morning. Our petrol wasted. Our time wasted. She had to put in an extra day leave. This is absolutely unacceptable. Who can I contact so that I can get my money back. This is absolutely ridiculous. Never ever will we make use of City to City again. I just want my money back.
