WHERE IS MY PHONE?

I SENT A CLAIM FOR ON 30TH MARCH FOR MY DAMAGED PHONE. THEY ONLY COLLECTED IT ON THE 25TH APRIL. THEN TODAY THEY WERE DELIVERING AND THE COURIER ASKS ME FOR THE OTHER PHONE. I INFORM THEM I HAVE NO OTHER PHONE AS NO LOAN PHONE WAS OFFERED THEN HE LEAVES SAYING HE WILL BE RIGHT BACK AND NOW HE IS GONE AND I STILL HAVE NO PHONE. I CALLED MTN AND THEY COULD NOT HELP ME!! WHEN AM I GETTING MY PHONE BECAUSE I DID NOT RECEIVE A LOAN PHONE BUT MTN INFORMED THE COURIER THAT I MUST RETURN A PHONE! WHAT PHONE MUST I RETURN?? WHERE IS MY PHONE?!!
