No customer interaction

extremely difficult website and on line chat. I cancelled the landline service on the 21 May 2018 , effective 30 June 2018, received a reference number, but the service has not been cancelled, resulting in charges incurred. I went on the website, as well as chatting with an agent online, no resolution to cancelling the service. i was told on the 21 May , that i will be contacted by someone to find out why i wanted to cancel, no call received. and no telephone numbers to call in to talk to a person.
