Complaint

Since January 2023 that I have given first complaint, Vodacom keep on phoning me saying they will sort out incorrect contract and short devise send. It is already May 2023, and still nothing has been done. In the meantime I have to pay more on my contract every month. Is this their way to make extra money from their customers whom has used Vodacom service since their existence? The last correspondence I received was in March, and I am still waiting for them.
