Poor Sales Service

I have been trying to OPEN a bank account for the last 3 weeks and every consultant tells me that I can only do on the App. All of them tells me there is a glitch on the app and they have escalated the issue and I should try again in a week. And guess what its week 3 and I still cannot open an account. I am hoping someone senior who actually knows how to assist would contact me and please resolve this matter.
