Pathetic service

Flight JE 712 date 29 March 2018 MANGO SCHEDULED to board at 14h30. It was postponed to 16h45 without notice to my wife. Then at 16h45 still nothing. Eventually they said 18h16. I Phoned the customer care line, had to hold the line for 11 minutes. The only reason supp**** was techical issues. The operator was also unfriendly My wife have a 8 month old baby with her. Pathetic service from Mango for not keeping clients updated. I understand the technical issues BUT let people know. But when a passenger is one minute late for boarding they are refused
