1 month old phone sent back, no phone for 2 weeks!

I recently purchased a iPhone 6 from MTN cosmonet at the Glen, the phone is damaged (display is loose) and I haven't even had it for 2 months. I went into MTN to have the phone sent in but I was told that it would take about 2 weeks and they don't give courtesy or temp replacement phones. How does MTN expect their clients to go 2 weeks without a cell phone, so basically I must still pay for the phone plus pay for a replacement phone while I wait. If I had known that the post customer service was this bad I would have never opened a contract with MTN. Now I'm sitting with a problem where my phone is damaged and needs a repair or replacement but I cant have it sent in because I don't have another phone. I cannot go 2 weeks without a cell phone.
