Incompetency and bad service

I open my account at Woolworth last year sometime and I asked them not to add any insurances, I later found out that they open 2 cover and have been fighting and trying to close these covers since last year, I have spoken to Bonita Matsone and Jenny Develious, their manager was suppose to call me on the 06 February 2018 but still nothing, Am here struggling to close these insurances while they are making profit out on me
