Data Protection Breach

I keep receiving a statements through to my email address that belongs to somebody else. This person has got a hold of my details and they have used them to open a bank account. I have sent numerous emails to them and they have informed me that this is being investigated by the ***** team and I will hear from them. This has been going on for 4 months. I have been calling the contact center only be to be passed around from agent to agent in different departments. I spoke to a gentleman in the ***** team and he told me that this is not his query and he doesn't know why I put through to him, advised that I need to to speak to the enquiry department, which I already had. The last call I made today, an agent by the name, Ayisha, said she will transfer me to the relevant department only to drop the line. This is not the first time an agent has hung up on me. I am disgusted and the service is appalling. No help at all.
