Red is the new Yellow for MTN

After purchasing airtime bundles and converting it to MTN SKY (2 day package) i find myself again' with no airtime. I went through this before and what a schlep to have this sorted out. I run a business and cant afford this lack of service and total disrespect MTN have for their costumers. The last time this happened, i am still waiting for a MTN "yello champion' to have it sorted out. In the meantime it costs me money for airtime that i do not get. i Had enough of this pathetic company. They should change from yellow to RED. Red, is all i see when seeing, dealing or hearing from or with MTN.
