NOT HAPPY WITH VODACOM

I have been using a router and iPhone contract with vodacom for a very long time.

And I was unable to use the data that is in my router because my router was ****** and I took the SIM card and put it in my tablet so that I can be able to use it unfortunately I was unable to use it until my contract ended so I told them that I am not going to renew a contract because I am unhappy as I am unable to use my data to the advice that I got was it will work on the router and I cannot leave a lot of data to go to waste so I agree to get another router but still I am not benefiting from my router whereas vodacom is deducting the money from my account every time.

So now I asked them for assistance today now they told me that the data is taken from my phone by the name that I don’t know, I am not benefiting.

So I need my data back of all the months that they took from me.
