False Advertising

I just used my loyalty points to buy data online after logging into my MTN account. I bought a 1 GB package for 2000 points however on approving and getting the sms from MTN it stated it was a 1 GB package for 1 hour only....Nowhere did it say on the dropdown menu of options that the 1GB data package was for 1 hour use only on the online platform. Got a picture to prove it. This is misleading and effectively false advertising. Won't be using their services again when it comes to renewing my contract. the amount is negligible, it's the principle that counts!
