Poor customer service

Flight je151 was sceduled for 16:46 OR Tambo to cape town on 29 Nov. However the flight was delayed until 18:00. Yet we only took off at 18:45. No correspondence was received from mango to notify me of the delay nor was there any announcement / explanation made once boaded as to why the delay ocurred. I tweeted my complaint to @flymangosa on Sunday but still no reaponse. It seems they only respond to positive feedback! Utterly dissapointed by the poor service or rather lack thereof! Will not be using their services anytime soon.
