NO HELP IN PORTING OLD NUMBER TO NEW CONTRACT - Consumer Complaint for Vodacom - Head Office

In December my boss was due for an upgrade. He was previously a Vodacom customer but had moved to Cell C. After being with Cell C and receiving terrible service, he decided to move back to Vodacom. As his PA I was helping him with this process. I went into a Vodacom store and they suggested that I apply for a new contract online so that my boss didn't have to come to the store. We did this application together online and we chose to get an iphone 11 (black 64gb) with a new contract that gives you 10gigs of data a month with unlimited minutes. Exactly what he needed. During the online process there was no prompt for us to enter his current number so that we could keep that number and port that number for the new contract. On the website there was a page to request to switch your number but when clicking on it (no matter the device) it doesn't do anything or it takes you to a page that does not exist. See picture. I then phoned a store and they said that when I received the device and the new sim I could then do a porting of the old number. So we continued with the process online and completed it. We received the phone just after Christmas and because my boss was on holiday we only looked at it again on Thursday the 14th of January. This is when I started the attempt to port the old number to the new contract. When going into stores and speaking to the online department including speaking to Vodacom over Twitter I was told that this was impossible to do and that my boss's contract is now on a new number. People kept telling me that I had to do it with the online process even though there was NO where to do this or to do it even before this. How was I supposed to know this as the customer. There was no way for me to know this. Even when I was directed online from the store they didn't warn me about this. As a person who runs two different organizations and is on the board of a third, my boss cannot afford to change his number! We have only been meet with people who are unable and unwilling to help or offer solutions. We thought and were expecting better service from Vodacom but have only been met with the opposite for the past two weeks. The contract is a lot of money a month and we are appalled at how we have been treated as paying customers. PLEASE, PLEASE, PLEASE can someone help us. We want to be a Vodacom customer and for it to be a pleasant experience.
