Overcharged bill

Good day

I hope this finds you well,

I would like lodge a formal complaint with your accounts department. I have been overcharged for the month of September and I don’t understand why and how. I have tried to contact the billing department multiple times and never get through instead I’m directed to a WhatsApp bot that cannot provide me with any assistance. When I call customer care I’m never directed to speak to a consultant which is something I don’t understand. Are we not allowed to contact the accounts department? Basically we get billed and cannot query anything because there is nobody to hold account? I want to understand the statement that I was sent? How am I charged R700 more my monthly payment???

Furthermore I got an sms stating my account has been suspended. How? When my account is update????

Can someone contact me urgently. This extremely terrible service.

Thank you
