bought a new contract and asked telkom to transfer my telkom existing number to the contract

Good day please note I just bought a Samsung S8 with Telkom carnival mall (staff Namgamso) on the 23 September and asked them to take my existing prepaid Telkom number and transfer it to be my contract number( ********** 102) as I don't want a new number. I have been using this number very long with Telkom. the contract was taken out on my my wifes account. To this date they haven't transferred my number( ********** 732) and my prepaid Telkom number just disappeared and a new number is no on my prepaid simcard and my contract still has the new number is was given when I bought the phone. please call me ********** 102. please also provide with your escalations department. I am tired that not one of the Telkom staff wants to take accountability for this matter. really pathetic services.
