MTN and Mondo

Took out a phone contract with Mondo (MTN), application was approved and sent with the courier company (Dsv),only to find out on the day of delivery the package was sent back to MTN by Dsv claiming I rejected the package when I didn't ...contacted the call centre and was advised they were not sure why this had happened to me because everything was in order...Mondo now redid an application which had dropped my credit from 693 to 300 something and advises me the second application is still pending, I must wait for a call, I was paitent but this is ridiculous, why must another enquiry be done on my profile when everything from my end was in order, now my credit score will drop again because of this. Everyday it's a different story with them but no process made...if you unable to assist please inform me and cancel my entire application but better make sure you have my credit profile back to how it was because I'm not accepting this nonsense... don't mess up my score and profile and still not assist me with what I app**** for.
