Horrible service from greyhound

If I could give a 0 star I would. Iv always spoken highly of this bus but they taught us such a great lesson. This past December we had a wedding and a funeral in the family so you can imagine the financial blow not to talk of the festive seasons. We purchased two return ticket for my aunt and nephew to return to Johannesburg. Tickets were purchased on the 26th of December for the 29th in the evening. The night before the traveling date, we randomly decided to check the ticket ND to our surprise, the departure on the ticket was marked as the 26th. We went back to shoprite were the tickers were purchased and they said that it wasn't their problem. Tried endlessly to phone greyhound but nob0dy ever picked up. Went all the way to cape town bus station and nobody could help us. No refund. No new seats in another bus, nothing. We met 3 other people at the bus station with the same complaint. We had borrow money just so we could sort out this mess. I swear I would never give greyhound another look again or even recommend them to anyone.
