Incorrect Personal Info Sent to Clients

I requested a letter from Edgars confirming that my account was paid up in full to submit to my bank on 26th August 2015. The lady at the branch submitted the request and called the call centre to request the letter, the lady and the call Centre said it will take up to 48hrs to send me the letter, I asked them if they could not just do it in the store as a simple Email cannot take so long They said no and 48hrs is what the turn around time was. I accepted that and left. I received the email yesterday and was very impressed with the quick service but that was short lived when I opened the letter Justin Soobramoney had sent me someone else's letter with all that persons personal details on it! I called the call centre yesterday and the guy said they will rectify the issue this morning and send the correct letter...I am still waiting. I also rep**** to Justin Soobramoney explaining what he had done wrong with NO response. How can you send a clients personal details to another client, This is why there is so much ***** going on because of idiots like this. I will cancel my account if this is not sorted out by today!
