The most disgusting customer service from CellC. Never take any products from CellC

The worst customer service I have ever seen in my entire life! My father has been trying to close an account for the past 2 years. Contract ended in 2020, he tried to close the account. He was told it’s closed only for him to be handed over to lawyers this year. He paid the outstanding balance this year March 2022, he paid it and requested closure letter. Till today none is willing to assist us. I have no idea of who can help us. Please can we get urgent help.
