Vodafone Business user - issue with connecting an Apple Watch 5 to an ‘older’ Business account

I recently bought an Apple Watch 5 with cellular capability on the basis that I thought I could then connect it to my Vodafone Business account, on which I currently have two IPhone 11 mobile phones, owned and used by my wife and I, and a SIM only number used to provide a 4G service when out and about with my IPad Pro. I was surprised to discover, having spent over £500 on the new Apple Watch, to be told by Vodafone that - purely it appears, because my Vodafone ‘pay monthly’ account is an older Business account - that the telecom giant’s ordering / billing system is still incapable of supporting an ‘e-SIM’ of the kind that the Apple Watch uses, and therefore that I am currently ‘ineligible’ to link the cellular facility on the device to my mobile phone account. The ‘fix’ suggested by a member of the Vodafone Business team, who it took a great deal of ‘research’ online to get hold of (the ‘default’ Contact option on the Vodafone website is to take one to a web chat) by phone, was that because I have an ‘older’ Business mobile phone account, I need to download and complete a Vodafone ‘transfer of ownership’ form to ‘transfer’ all my existing account-related data to a ‘newer’ Vodafone Business account, to give me the ability to then get my cellular Apple Watch 5 connected to the mobile phone account.

This in itself seems laughable, but I was then told that once I have completed and submitted this form, it ‘could’ take up to 90 days for Vodafone to process the change and thus give me the cellular capability I need on the Apple Watch to be able to use it out and about away from Wi-Fi when without my phone. Why, as longer-serving and loyal Vodafone customer, should I be being penalised in this way? The excellent independent mobile phone shop in West Kent that has ‘administered’ my Vodafone account for over 20 years has now intervened, and is trying to resolve this direct with the Account Manager within the Vodafone Business Department that they deal with. For a large mobile phone provider not to be able to offer ‘Business’ customers cellular connection to a proven, and in many ways, ‘state-of-the-art’ device such as an Apple Watch, which is an excellent communication tool, simply because their billing service cannot support this, is absolutely unbelievable. This crazy scenario is made even worse by the fact that nowhere that I could see quickly on its website, does Vodafone make clear that some of its ‘Business’ customers will encounter this issue. Perhaps somebody from Vodafone would like to comment and explain this glaring anomaly?
