Incorrect billing and overcharging on an expired

Vodacom overcharging like they always do, money hungry and does not review their systems at all. I'm being charge for a device that is suppose to expire and have not been reviewed, it shows on the account that it expired 1st of July, but yet here we are, being charged for August, and now the account shows that I will be billed for end August on an expired

Please refund for that bill! And ensure that I'm not charge again! I do not care to be contacted, as you will spin up nonsense for me like you tend to do, and say oh no not your fault. Where is your customer obsession? Why do your customers have to suffer for your systems? Why do I need to be inconvenience for your issues?
