Unfair poor service

A cell c sales agent approached me to take out a wift/fibre contract. She advised it was 1 month free and you can cancel at any time. It was February this year.She advised the 1st payment wll oly be ducted in April. Howeer they started deducting from March and did not stop. I sent an email in March and todate am waiting for their response. My ex landlord also forwarded the emai lto them regarding he cancellation as I had moved from her property and they needed the new tenanat to connect fibre. They have listed me on ITC. This is unfair poor service. My accont went into arrears with unpaids due to their deductions even after I called them, They are ******* and do not deserve customers. Am very unhappy. I called them today again. The customer service agent was going to transfer me to the fibre department and instead cut me off. She didn't call back to apologize. Their service sucks
