No response - Call Centre telephone and e-mail

I have a deposit refund that's due to me following closure of my municipal account. For the past 2 weeks I have been calling the Call Centre to follow up on the payment. The call get's answered by the electronic answering machine. I have chosen the options as prompted but no one picks up. I have called more than 10 times in the past 2 weeks. I even sent an e-mail on 1 September, no one has responded.<br> <br> This is really bad service!!!
