Poor Customer Service

On the 5th of November I checked into the airport, about an hour before my flight to East London. Upon checking in, I was required to go to gate E7 . Not knowing my flight was actually leaving on gate E10 . No one bothered to inform me or anyone that was left behind on gate E7 . Anyway we were then advised to go to the help desk , where clearly it was more than one person that got left behind . They booked us out again on the first available flight which was for the next day . The airline never took responsibility for accommodation , as an individual you must make a plan and see what you can do but they made it clear accommodation won't be taken care of even though the mistake came on there side . This was my first-time using this airline and my last . I am so disappointed in them- lack of communication I wouldn't recommend this airline to anyone.
