Dstv internet is a ****

Dstv internet is a ****.I Paid my monthly subscription on the 2nd of March and today on the 13th of March the data has not been loaded.When I call they tell me that the Sim number is not showing on their system and they apologize and escalate the issue.Today I called for the 9th time and still I have no internet after the call.I tried to cancel the contract but it seems like it's a mission impossible.Stop ******** people
