I firstly paid for showmax for the past few months this year, n didn't get, then I purchased their internet and the choose to give me the one with the smallest amount of data which doesn't even last two weeks, then calling them, while using my airtime and they take forever to pick up while airtime is being lost in the process of that, when they get to pick up the call, I spoke to a friendly person and asked for a upgrade to the last data package, and now it doesn't work from the 15th till today, and I still request a call on the what'sapp app, but till today nothing, I then again think maybe it's because I have not paid... I pay and send the proof of payment on the what'sapp account, but still nothing...
