Vodacom, Really sad to say

It’s been 8 months since the ***** occurred on my account, and I reported it the next morning. I’ve faced 8 reverse unpaid amounts and incurred bank fees, not to mention the impact on my credit score. Despite making my payments every month, they still can’t resolve the issue. I’ve been trying to address this problem for months, but when I call them, they block me. I suppose that's one way of avoiding responsibility.
