MTN Lost phone during repairs

<p> I took my phone in for repairing during April at a MTN shop. According to the staff at the MTN shop, they immediately send the phone to their "repair centre". After a couple of days I called the MTN shop to find out if I could perhaps fetch my phone. The MTN shop then told me that they haven't received my phone yet. I got suspicious and anxious because almost two weeks had passed so I decided to phone the MTN "repair centre". According to them, they couldn't fix the problem (IMEI was wrong etc) so they decided to send it back to the MTN shop.</p> <p>So... I went back and the staff at the MTN shop denies the whole story.</p> <p>It's two months now - NO phone, no NOTHING except for the fact that my money goes off my bank account for a phone which MTN stole/lost???!! </p>
