No response to email, harassing calls instead

<p>On 9 November 2015 I sent an email to Personal Lending and Information regarding my cheque account. I did not receive a response. I sent a follow up email to the same on 7 December. Again, no response. Recently, I got in contact with a certain Jessica Stevens who then directed my query. Instead of the email query being responded to. I am now getting harassing phone calls from call centre agents. Last week I spoke to a Thulani from Cheques and Loans Department. He advised that he would get the manager to call me but nothing so far. I then wrote another email ********** on June 15 2016. I still haven't received the required response. Instead the call centre agents who have no idea what's going on keep calling on a daily basis. Can you respond to the email!!!</p>
