I have a " relationship savings '' account with TD Bank. Because this savings account has a " relationship '' with my " relationship checking '' account, I am entitled to a certain rate of interest. XX/XX/XXXX about 10 months after the accounts ' set-up, I was fed up with the ridiculously low interest rate of this " special '' account and I went on-line to look at other accounts. I discovered that I had been receiving an interest rate of only about XXXX of what it should have been. I notified my TD branch in XXXX MA, and they discovered that my relationship accts had not been set up properly ; so they linked my accounts and gave me my retro-active interest. After that, I began to compare my monthly statement 's stated interest rate with the TD Website 's stated rate. My XX/XX/XXXX statement showed my interest as less than XXXX of what it should have been. I contacted TD and it appeared that my savings acct had been de-linked from the checking acct. This was fixed, but only after a great effort on my part. The XXXX number follow-up never occurred and I had to contact the manager of my local branch. The next statement still had a higher, but still wrong, interest rate and did not reimburse me what I was owed. On the next statement XXXX XXXX ), the interest rate was correct and I recieved {$20.00} which included my retro-interest plus a small bonus that I insisted on, not only for my trouble, but also to penalize TD. I emphasized my concern that many other people may be suffering from this same problem without knowing it. On the XX/XX/XXXX statement, my interest rate was close to XXXX lower than it should have been. The local branch manager gave me a credit that was about XXXX cents more than I was owed, as a bonus. My XXXX statement also had the wrong rate. It took some time to figure the cause of this error ; there were a few theories, but in the end, it was simply the same problem that my relationship savings account somehow got de-linked from my relationship checking account. This time I went higher in TD 's hierarchy to a XXXX Manager in XXXX XXXX XXXX XXXX, XXXX ) and recieved retro-interest that was a bit more than what I was owed, and I recieved a {$25.00} apology amount. XXXX XXXX also apologized profusely by phone and promised to launch an investigation. I told him that I was on the verge of contacting the government because I was so concerned about other unknowing victims. My dealings with him were XX/XX/XXXX and my XXXX statement was correct and contained the money he promised me. I just recieved my XXXX statement and again, my savings interest appears less than it should be ; it is .37 % ; which is less than the .4 % which has been the stable rate for many months. I can not confirm this because my type of account no longer appears on the website, but in this economic climate, I can not imagine that the interest rate, in fact, decreased. Yesterday, XXXX XXXX XXXX, I emailed my branch manager and left a voicemail for XXXX XXXX. No replies as of now. Even if this month I prove to be wrong, which I can not imagine, I would like your office to investigate TD regarding the proven problems which I have described here. I am very, very concerned about other people recieving less interest than what they are entitled to. I wanted to file a complaint sooner but have very limited bandwith and could not find the time and energy. Until now. I can follow up with TD each time this happens to me until I am fed up enough to close my account, which is a time fast approaching. However, the population needs to be protected. Even if TD 's errors are accidental, TD must be forced to fix its problems. I do not believe that I could be the only victim of such errors. I do believe that most people would not be aware of such errors and/or would not be able to resolve them on their own. Thank you so very much.
