Ethically and morally disappointing of SAGE South Africa

i signed a 3 month support contract with Sage in Aug 2019 however they continued deducting monthly thereafter despite the agreement stipulated i require them to support for 3months only. Other options were available however i didnt tick those as they werent required. They did not provide any support post the time period and even telephonically told me i could call and cancel at any time within the 3 month period. This goes outside of CPA. Ethically immoral and they wont provide telephonic copies of discussions with me. Contract signed clearly states 3 months
