Doesn't reply to service request and avoids my questions about interest charges

<p>I would like to know why i get charged multiple interest amounts per month on my RCP, however, no one can provide a real reason. The one agent that assisted me logged a service request because the agent also thought that the multiple charges doesnt seem correct to her. Its more than a week now and nothing has happend. I would like clarity on this and i would like to know how an account that is not being transacted on, gets charged on interest multiple times per month.</p>
