Vodacom Frustrated Customer

I have never been so frustrated in my life. I app**** for a router contract with vodacom in February 2023. I am suppose to be paying R350. Yet the last 2 months I've been billed with an exorbitant amount of R1 979. I went to the vodacom shop to make an enquiry of this. They told me I subscribed to some entertainment service of which I'm unaware of. They told me I need to call customer care and ask them how I joined this and how to cancel it. When I called customer care they put me through to accounts. The accounts services explained what they should have done at vodacom store and sent me back to Customer care. I'm very much frustrated by this. Becuase they keep giving me a run around. I've had a contract with another service provider. But theyve never treated me this way. Im very much disappointed and frustrated with Vodacom. I wish I could get some sort of assistance to cancel this unknown bill.
