Continual delay in flight to Cape Town JE151

I booked a flight on. Mango Airlines 5 months ago. I received an sms two months later advising that the departure of the flight would be delayed by one hour. Today I received another small advising that the flight would be delayed again by three hours so a flight that was supposed to leave at 16h35 is now departing at 20h35 (4 hours later) really shocking service considering it is peak holiday season for South Africans . We are now only going to arrive in Cape Town tomorrow evening 26th December at 22h 45 , if we are lucky,<br> <br> Really disappointed,!!!
