Bad Customer Service

So much time and effort go into sales and training yet when they get a sale they cannot deliver. The sales agent from Mobile Plus called us to upgrade our phone. We got a notification that it's on pause has it requires a document. We have been calling from the 19th to inquire about what document is required and over 20 people have transferred our call to the next person in which none of them as assisted. Please send this mail to the CEO to see that they are not representing the MTN brand in a good light and to check up on why they are not being trained to provide a good customer service. We have spent days calling MTN and no one is helping us. We are still waiting!!!
