Conflicting information

I am on a business package and qualify for an upgrade on 20 July. I phoned the call centre (082 111) to see if I could get an early upgrade based on my average spend, and if I upgrade my contract. I was then put through to the business centre (***). They told me they don't deal with upgrades and transferred me back to the call centre. They told me they don't do premature upgrades anymore and don't deal with business accounts.<br> <br> Please can you clarify the situation with premature upgrades and who should be contacted. Thank you.
