Still getting advertising calls

Re: Please find your reference number: ***/GO<br> <br> Despite a promise to stop unsolicited calls, I today again received an automated call offering me cell phone insurance and a chance to win R10,000 all for R19.95 per month on my Edgars account. <br> <br> The recording is available if required. <br> <br> Do I need to close my account at Edgars and no longer do any purchases there to stop the unsolicited calls or perhaps make a case in terms of the Electronic Communications and Transaction Act (Act 25 of 2002)(ECTA) as read with section 11 of the Consumer Protection Act (Act 68 of 2008) (CPA) or section 69 of the Protection of Personal Information Act (Act 4 of 2013)(POPIA).<br> <br> Your urgent response is required as failing to comply with my request constitutes a ******** offense in terms of section 45 of the ECTA and may lead to prosecution and resultant damages claims.<br> <br> Your offer for me to call you on 0800 ***X is unacceptable as I need proof of my requests in writing.
