The promotion is conflicting with the business rules

I have been a loyal client of Telkom for more than 7 years now, Telkom was promoting their "new" product (https://mybroadband.co.za/news/adsl/351995-telkom-cuts-uncapped-adsl-prices-starting-at-r199.html) . I called their contact centre(Sales) to enquire regarding the migration to this product and was advised to go into a Telkom store. I went to the Grove Mall Telkom store and the agent at the store, firstly was not aware of the product and afterwards advised that I do not qualify for the this product eventhough according to the article "This product will be offered to new and existing customers, who will receive the benefit of higher speeds." I am not using my voice line and find it a waste of money paying for it. My humble request will be to be migrated to this product urgently, please contact me asap! The promotion is conflicting with the business rules.
