Misleading data bundles and useless customer service

The app was misleading when buying data, it says "15GB - 500MB everyday". In those words it says to me that you buy 15GB. But when it went through I see they give you 500MB for that day that expire the next day.

Why put that 15GB there? To deliberately mislead people? I tried to contact them afterwards and sat on hold for over 30 minutes getting the "we are transferring you to our next available consultant" on repeat, for a half an hour with no answer.

This was my next step, if the consultants actually answered I wouldn't have to go through other means to contact them.
