Refusal to cancel service/adverts

In February 2014, I was approached by Trudon to place an online advert for my business, plus an advert in the Yellow Pages at the end of 2014. <br> I never approved the Yellow Pages Proof, and on 5 September 2014, I emailed them and, requested Trudon to cancel the online advert, and requested that they not publish the advert in the Yellow Pages. <br> <br> They ignored this instruction, continued with the online advert, and went ahead and placed the advert in the Yellow Pages.<br> <br> I received a phone call on 8 April 2015, from a Trudon sales representative, who was pressurising me to renew the online advert. I was very definite in saying I did not want the advert renewed. I confirmed this instruction with an email on the same day. <br> <br> I received my Telkom account dated 23 April 2015, and noticed I am still being billed for both adverts.<br> <br> I an not happy with the ********* business practise of Trudon, and request that action be taken to rectify this situation.
