Worse service ever, what the hell?

Worst client service ever, you can't complaint about the service because their aren't any. Staff inside the bank are willing to help, but it seems that it's out of their hands as well because their head office is dysfunctional. I have opened an estate account 25th of November 2020 for my late mother's estate. I was promised that it would only take a couple of days to be finalized and funds to be transferred. The estimate time, I was told that it would be done within 7-14 working days. Since then I had to follow up with them several times and every time I get told that it will take another 7-14 days to be resolved. How many times must I wait for 7-14 days, now were on the 20th of January 2021, and still no feedback from them. How do they expect a client to put trust into them with your finances? Her account needs to be closed, and the funds transferred to the opened estate account, how difficult can that be? They don't get back with any feedback. The banks were not closed over the Covid period, they are using this as an excuse. This is absolutely unacceptable. Your communication sucks!!!! What the hell? Finalization is long overdue, don't you think!!!! How must I as an client put my trust and money into a bank that is not even getting back to me with decent client service, how safe is my money in the bank and how can they be trusted if they can't even do the basics on client service.
