Product: Credit card or prepaid card

When I opened the small business credit card account reacting to {$750.00} marketing cash back offer at {$7500.00} spent within 120 days, I was told that the company will honor the offer. Since the credit limit was sent at {$1000.00} per statement ( despite having a XXXX credit rating and no debt ) I was told by the US Bank Executive team member that in order to overcome the {$1000.00} limit and still meet the required spend I have to keep making payments at {$1000.00} intervals to free up credit for the transaction. This worked until XXXX when all of the sudden and without warning the US Bank decided to transfer the payment to a central payment escrow account thus freezing the available credit at {$1000.00} regardless of positive balance exceeding it. I attempted to work with the bank using following : 1 ) close the other US bank credit card account to increase the available credit : denied 2 ) increase the credit limit available : denied but available after 180 days review period which will put it behind the XX/XX/2022 {$750.00} marketing offer expiry 3 ) requested to have the offer to be extended to XX/XX/2022 ( an additional billing period so the billing spent can be met ) ; denied. 
4 ) requested the payments to be made to the card directly instead of the central payment escrow account : denied. I was told that the transfer of the central credit payment to direct credit card payment will take 1-2 billing cycles thus it will take place after the expiry of the XX/XX/2022 deadline making it useless. 

I was also not informed why the central bill pay is mandatory at the US Bank as the company is actually holding the money in escrow instead of applying it the very day it received it but I was informed that it is done " automatically. '' This is despite the fact that I didn't ask for the billing to be done this way and contrary to my wishes. Subsequently the bank also denied a confirmation that the transfer of the central pay escrow to direct card pay will not affect the points already accrued on the account as result of the transactional activities. 
So in the last pay period I have had the following totals ( since XX/XX/2022 ) : {$300.00} positive balance {$1000.00} payment {$630.00} payment {$1000.00} credit limit {$2900.00} ( that if direct pay should be more than enough to meet the {$7500.00} spend ( as of XX/XX/2022 : $ XXXX XXXX {$7600.00} ). 
However as of today the card despite reaching an overall limit of spend at {$7000.00} ( {$480.00} more to go as of XX/XX/2022 ) the transactions going forward are being rejected : XX/XX/2022 {$90.00} XXXX XX/XX/2022 {$14.00} XXXXXXXX XXXX XXXXXX/XX/2022 {$54.00} XXXX It is obvious that the US Bank is blocking these transaction on purpose and keeping the payments already made in account pay escrow so the {$7500.00} is not met thus the offer 's terms will not be met by XX/XX/2022. 
After the offer deadline passes the US Bank will apply the credit to the account however it will be too late to collect what is owed. It is very disappointing that the US Bank will be playing games such as these and structuring its credit products in bad faith so the customers are not made whole. I attempted to be flexible and offer the bank several ways to address this issue but not to avail. It also appears that the advice given to me in XX/XX/2022 to address this problem by the US bank executive office was given in bad faith as shortly after my payments were stopped being credited to the account and sent instead to the central pay escrow.
