Only received 1 phone paying for two

I was approved for 2 separate contracts for the Samsung A53 5G so that means 2 phones and 2 contracts for R500 each p.m .on MTN I received only 1 phone and was sent the payment mandate for a debit order of R1000 pm for 2 phones. I'm getting the run around now between mondo and mtn .where is my other phone? If you go to your recordings you will pick up I was approved for 2 phones and 2 contracts. Kindly note I will suspend the debit order until this is resolved I can't pay for 2 contracts if I only received 1 phone. Thank you! I keep on emailing and trying to call with no luck.
