The service is quite poor last year renewal my contract still awaiting for my cellphone contract renewed with consultant Cassius Ngocobe.Yoy signed a contract with mtn for 36 or 24 months but Mtn still goes and increases your monthly payments in Feb and April what's the used of signing a contract.They tell you cause of load shedding, battery thefts and petrol what does this to do with the price of egg.You signed a contract to pay fixed rate until contract expires.They are actually unfair towards the consumer
