Urgent Inquiry Regarding My Monthly Bill

Urgent Inquiry Regarding My Monthly Bill.Good evening Vodacom team,Last week, I received a call from one of your consultants, an Indian gentleman, who informed me that my monthly bill would be reduced by R20 because I was being overcharged. I even questioned him about the significance of a R20 reduction, to which he responded that it would still be a saving. I agreed to the adjustment as I was paying R353.53 per month.A few days later, I received an SMS requesting my proof of address, three months' bank statements, and my identity document. I did not send these documents. However, today I received a message stating that my bill for December is now R535.56.I am deeply concerned and frustrated by this situation. During the call, the consultant explicitly assured me that my bill would not increase and that my contract would not be extended. How did you proceed with these changes without me submitting the requested documents?
