Customer Service Nightmare

I'm writing this to express my discontent with your call center team.

I started the process of updating my details to access my account on the 14th of April and after endless back and forth communication my details still have not been updated.

It seems to me that my query is being handled by multiple agents,(I counted 5 names on the email footers) who do not respond even if I reply within less than an hour.

I would access my account and my funds. and my frustration stems from what i believe is poor customer service updating 1 person's details should not take a whole month to process and i fear that even once it is updated accessing my funds could take another month

I kindly asked for my matter to be escalated yesterday and the lady I spoke to said she would but when I called today for feedback the agent advised that there was no escalation logged.

I want access to my funds which I have left in your hands since 2000 i do not believe that i have been given quality customer service and i would again like to ask that my matter be escalated
