error contract

I recently purchased a device on Vodacom online. Device details are as follow Apple Iphone 14 pro Gold 128GB @ R1079 PM for 36 Months on RED FLEXI 245. I SPECIFICALLY REQUESTED THAT THIS CONTRACT SHOULD BE REGISTERED AS A SECOND CONTRACT BECAUSE I HAVE AN EXISTING ACCOUNT, AND I ALSO REQUESTED THAT THEY CONVERT MY EXISTING CELLPHONE NUMBER INTO A CONTRACT FOR THIS NEW DEVICE.

TO MY SUPRISE WHOEVER CAPTURED MY ORDER REGISTERED A NEW CELLPHONE NUMBER FOR MY CONTRACT.. I TRIED TO GET HOLD OF THE VODACOM AGENTS VIA PHONE CALL BUT I AM BEING SENT FROM PILLAR TO POST. I EVEN WENT TO A VODFACOM STORE FOR ASSISTANCE BUT I WAS TOLD THAT I CANNOT BE ASSISTED BY THEM BECAUSE I DID NOT PROCESS THE ORDER FOR MY PHONE WITH THEM. I cannot pay for the contract that I am not receiving the airtime for honestly
