Telkom ruining my Business

Absolute ******* "customer nonexistant care". I have a new contract taken out on black friday, went to the Telkom store after receiving new phone and contract number, requested that they move my existing prepaid Telkom number to the contract on 12 December, got a call from a person on the 21st December to port the Telkom number into the contract, he advised maximum 72 hours, it is now January 4th and I have no service on my original nber which I wanted on my contract. I have had this number for approximately 20 years and now nobody can get hold of me, nor can any of my passwords linked to this number work anymore, I also cannot use whatsapp on the new phone as I need this number to work for my WhatsApp. I call in everyday and get given the excuse of it has been escalated, ask for reasons on why it is taking this long non given, when will it be resolved... They don't know. Please advise if there are any other channels I can escalate through as all I want is my mobile number back even if it is on prepaid. My case ref is ***1. I am a business owner who is now unreachable.
