Harrassment

Harrassment, netstar handed my account over to this company which an arrangement was made on the 12th of November 2020, however I called the company between the 18th or 19th November to arrange with them an updated banking details were I was told an agent will get back to me . The 26th November i called for a follow up why there was no feedback the only feedback I received was the amount has now increased, when trying to dispute this I am referred to agent after agent until I got referred to a manager called Abeeda Titus yet the amount keeps increasing yet I took full responsibility of calling and changing banking details in time to varify however I am told about extra charges. They agents call me daily which I now feel it is harrasment.
