FIXED RATE Error and disgusting response

I have logged a complaint about the fixed rate form since June and it has not been resolved to date. I requested a quote for a fixed rate, and I was sent a form with someone else's name on it and I made them aware of the error on the form. I was sent another form with just my name, on it which I opted not to sign until confirmation of the actions taken for the "original form" was received. I did not receive any confirmation except the mails advising me that the fixed rate option was being actioned, followed by a confirmation of completion of the request for a fixed rate. I wrote in to query the irregularity on the "Original form" due to the other name of another customer who is not a party to the account, and the response to my request was nothing short of disgusting. I was told that the name on the form is a NULL value and the letter was addressed to me. This is apparently their "NORMAL" process for all single bond holders.. This is nonsense and I rep**** back to the info thereafter I logged a complaint regarding the matter and it has not been resolved in the meantime I am being charged the "FIXED RATE". This matter has been dealt by so many people including their customer complaint centre and their Private banking consultant and they all failed to resolve it. I absolutely need help to address matter and close as soon as possible, this has been going for 2 months now, since the 5th of June. Thank you
