No Customer Service

I sent an email to DirectAxis disputing some charges to my account. I received an automated response email saying that someone would provide feedback within 48 hours. my email was in February . Yesterday I get a call saying that I owe them money. I ask if my email query had been resolved. Response was what email. When the consultant read the email he said that they had tried to contact me but could not get through on my cellphone. I attend loads of meeting so calling me on my cell will not be the best solution. I asked why a written response was not sent to me ans he rep**** that they do not respond in writing. This is in contravention of the NCR Act 2005, which states in section 111 "A credit provider who receives a notice of dispute in terms of subsection (1)- under a credit agreement, by delivering a written notice to the credit provider. (a) must give the consumer a written notice either- (i) explaining the entry in reasonable detail; or (ii) confirming that the statement was in error either in whole or in part, and setting out the revised entry;" The consultant I spoke to yesterday promised that a manager would call me by close of business yesterday but as usual nothing happened.
