Data lies

Got an M-Kopa phone in Aug 24. The agent who assisted me advised me to buy my own sim which I did. Not once was it mentioned that they would provide a SIM card with the phone. I was also told that I would be allocated 15GB data. Fast forward to Dec 24 and no data has been received yet payments are made on time. Reached out to them because they clearly have no courtesy to contact those who have complained about this issue to update them and I am told “the policy was updated on the 1st of December 2024 by the network provider. You are therefore in eligible for the data”. Terrible customer service
