disappointing service

Took cellphone contract with mtn online on the 28th April. Till date I have not received the phone. On the day that it was meant to be delivered, I was informed the courier guy was hijacked and I would receive a call to reschedule another day for delivered 2 weeks went by and I still have not Received anything , I decided to call Dsv couriers because to find out way forward they informed me I should call Mtn they will assist . I contacted Mtn to be told I should like their contracts mondo . Of which I did and was referred to rewards co. An incident has been logged but till date I have not received any feedback . But what type of customer service is this honestly ??????? What does one have to do to get assistance . Apart from the time , distress and airtime I’ve been spending call services of all these organisations I still don’t have a resolution
