Dishonesty and disatisfying service

Last month around this time I complained about the poor and inconsiderate service from vodacom. I requested a premature cancel on my device in April 2024 and I paid the full amount within 7 days. This month vodacom debit triple my normal installment. I want my money back in to my account. I'm sick and tired of this inconsiderate service from vodacom. We follow procedures given by them when they supposed to render quality and satisfying service all we get its different explanation from their customer care advisor. I want my money. This is the second time I complain about the same thing on this platform
