still no delivery from

On the 26/09 i was contacted for an upgrade for my contract which i gladly took since i need a new phone, I was informed that i would receive the phone within 7 working days. On the 2/10 i was contacted by dsv which is the delivery company to inform me i would receive the phone on the 3/10. On the 3/10 i then received an sms confirming the delivery for that day which was never delivered. I called mtn on the 4/10 they told me to call dsv which i did and then dsv informed me that mtn recalled their fleet with my package and mtn was supposedly supposed to call me which they did not. I then called mtn again spoke to a lolo who told me that her supervisor would call me back and he never did. Called Mtn again on the 6/10 spoke to zuko who also told me his supervisor would call but never did... I called again before 5 finally spoke to the supervisor lungile who was meant to transfer me to the right department but never did. Dsv then called again on the 7/10 spoke to lufuno who called to confirm another appointment for the 11/10 ... Nothing still ... im very exhausted, disappointed and ****ed off
