The in-branch account opening went fine but the issues started popping up afterwards. I enrolled in online banking later in the day on XXXX to initiate connections to external bank account for funding and everything was working on XXXX when I went to login to online banking I could login but then the account was no longer an account tied to my online banking profile. I tried again on XXXX with the same result so I called customer service, and they said I needed to contact the branch in which I opened and the business banker would have to work on my issue. Called the branch and the business banker was on vacation and there was an interesting game being played of which some employees would say they do not have a branch manager at the branch and some would actually give me the name of the branch manager. On XXXX XXXX of the employees saying there was no branch manager asked if i could call another branch, called a different branch and spoke to the business banker, said they were going to look to the issue and they would call me back later that day. Heard nothing and called again on XXXX and the business banker still said they were fixing it and someone would call me back later that day. Heard nothing so on XX/XX/XXXX called the original branch where the account was opened at and asked for the business banker, spoke to someone that said they would try to help but nothing happened. On XX/XX/XXXX called the branch again asking for the business banker, they refused to take the call. Called and spoke to customer service and they said they would email the branch as they think they know the fix, once again heard nothing. On XX/XX/XXXX got a call explaining that they changed systems and my business checking was opened in the old system but not the new system and that is why my account disappeared. On XX/XX/XXXX finally landed the requisite amount of funds into the account and started the process of making the required debit card purchases in which all debit card purchases where completed on XX/XX/XXXX. It is now XX/XX/XXXX which is XXXX months since account opening with no bonus deposited. I have attached the promo page and the transaction log showing the deposits and debit card purchases. I can provide the branch location in which I opened the accoount
