On XX/XX/2018 ; I opened an HSBC Premier account online as per the rules of an offer from HSBC, so I may obtain a {$750.00} bonus from them. 
On XX/XX/2018 ; I added my wife as a joint account member at a local branch of HSBC in XXXX PA, and fully funded the account over {$100000.00} that day, using a combination of Premier account funds and a Certificate of Deposit, as per the qualifications of the {$750.00} bonus offer. 

The bonus offer stipulates a minimum balance of {$100000.00} must be maintained for 90 days and afterward a {$750.00} bonus will be given within the following 60 days. 

We have maintained a balance over {$100000.00} FOR OVER 190 DAYS NOW AND STILL HAVEN'T RECEIVED THE {$750.00} BONUS FOR THE HSBC PREMIER ACCOUNT. 

I have contacted HSBC 6 TIMES now, and they have agreed on several occasions that I have qualified for the bonus and should have received it. 
They have stated 4 times that they will look into the matter and call me back but did not call back on the dates they said they would call. 

There were 2 occasions I did receive a call back to be told there has not been an an answer to when the bonus would be received. 
I see many other complaints online regarding HSBC falsely advertising an account bonus and not paying the bonus. 
It is nearly 7 months since my account has been opened and fully funded. 
I should have received the bonus within 5 months per HSBC, but I have not received the bonus. 
Seems like HSBC is fraudulently offering a bonus to lure in customers. How else should I feel?

HSBC needs to pay us the {$750.00} Premier account bonus or be held accountable for fraud and false / misleading advertising, and face severe financial punitive damages for knowingly doing so and failing to take corrective action.
