Porting my number from Vodacom to Telkom taking months? Why?

In December 2017 my contract with Vodacom ended and I changed to prepaid. Then I signed a new contract with Telkom and requested the porting of my mobile number from Vodacom to Telkom. After 3 months and many emails, branch visits and phone calls, I still cannot receive any Vodacom calls or sms messages. Cell C, MTN and Telkom calls are routed, something is wrong with Vodacom numbers. Vodacom had confirmed that they have released the number and that Telkom needs to complete the porting. May the Telkom technician please complete the porting. Surely it is just a button to press....
