Mobicell

My phone is still with mobicell they dont say anything..I dont see why should i pay for a phone that is still on warranty..And why are they lying saying my phone has liquid when they know bery wll they are lying. Never ever buy from them they dont treat their customers with respect the only thing they want to do from customers is to take money from them,as now they want me to pay R985 for fixing my phone for a phone i bought with R1200.How is that fair to a customer..?CROOOKS
