Where did i sign that i agree to wasp services and agree to have money deducted for it?

Since my last complaint i have not had word from the customer relations department: The only thing i know now is that of the 4 subscriptions currently showing on my phone i can not unsubscribe from any of them.

Worst of all i have not been using my vodacom sim for outgoing calls, and my balance of R150 per month has now gone down to R82. So R68 has been decucted by this services i did not and definitely do not want under any circumstances. I think that everybody with these type of issues should speak up. Where did we ever sign for this services? Please show me on my original vodacom subscription contract where i agreed to this? Or is it hidden somewhere in the small print? Or is it closeted under operational procedures? Since i can not foresee that a 3rd party service can become a operational procedure or necessity if whatever 3rd party was not a member of the principal company namely vodacom at that time that i signed the agreement. Since in my very limited legal knowledge a addendum to the primary contract would then have had to be signed by myself as well as the service provider. One thing I know for sure is that i am not going to renew my up contract again if things do not get sorted out, or investigating the porting option. Because really i mean i have had a lot of patience so far, and as life goes i really have more important things to concentrate on than my diminishing airtime due to wasp services.

Please, please give this issue all possible attention, so that we may be able to resolve this amicably.
