Website has bugs and get zero support

Tried to open an investment account at FNB. At the last stage of the process, their website crashed - a message stating that FNB would look into this. I have no idea if this account was created or not, so tried their online help. Got through to a person called David Thekson. Wrote my story to him, and got zero response. I tried asking him to acknowledge if was there, part of the conversation, and got no response. 10 minutes later, the online chat was closed, and I was placed back in the queue. I still have no idea if the account was created or not. I would like to invest this cash, but will not be doing so with FNB. Just would like to know if this account was created or not, so as not to open 2 accounts. Added to this, I pay extra banking fees each month (as a platinum member) to receive higher rated service, but this doesn't mean anything, when the help desk doesn't even respond. Perhaps I should move all my bank accounts away from FNB - why am I paying more for zero service, and a website with bugs????!!!
