HP Instant Ink

I currently am a instant ink user and have been for years. I still use a printer that isnt even eligible for warranties, repairs, etc. 

I just now seen this platinum instant ink so i immediately tried to take advantage because im also currerntly in final process of getting a home based business started as an extra income. 

I couldn't find any option within anywhere of my instant ink account regarding upgrading or even mention of it. I planned on creating a new instant ink account later on for my business and would cancel this one but i went ahead and created it after initiating instant ink platinum on the hp site. No issues creating account, i get through all the steps given on starting instant ink platinum, hit sumbit and it keeps saying "failed to submit request. So wondering if i can get answers for both variations i spoke of. 1 being if there is an option to upgrade current instant ink account to platinum how do i do so.

The next would be what it the issue regarding trying to start on my newly created account. Could it be a payment related error for example, do i need a particular amount of money on my account? It says my card wont be charged upon submitting for platinum service but getting down to fine print stuff, is there a pre authorization type request its using when accepting my payment method, if so what amount needs to be in there so it comes back as i have enough money to cover the service and included printer. I can easily make my debit reflect having any particular amount its looking to see. 

Then if not what else could it even be ?
