Porting Trouble

I have been trying to port my current number to Telkom after taking out a contract in April 2021. I received my device, and am currently being billed from the 26th April 2021 from both my previous service provider and Telkom. I have been to the Telkom store at Liberty Mall PMB on the 27th April 2021 and the agent said that the port would take place within 24hrs, it is now a week later and nothing is done
