Mango delays and inefficiency

As a frequent mango flyer, I am very disappointed in the service delivery as my flight was just over 3 hour's delayed on my departure as well as just about 2 hours on my return with notification 5min before boarding. As a multiply mango member this is pathetic and makes both momentum and mango look bad. I called the mango call center today and spoke to Patience who told me that the complaints department is closed over a weekend, she also said there's no managers or supervisors to assist me so I must call back on Monday. So on top of mangos delayed service even the call center seems inefficient. How long Will this carry on for and what's the plan of action going forward as im a frequent mango user and Will not recommend mango to anyone. Dissatisfied customer.
