Round 2 of bad service Rain 5g

So this is my second time reviewing Rain within a week, my internet was on from Thursday 9 June 14:00pm and off again on Monday 13 June, so my thing is I called yesterday after explaining to the support agent all the events and also she should please call me back when my airtime cuts, I heard no response, it was like I was muted, my airtime ran out after almost 4 mins, and still nobody called me back, so even logging a problem on the app it's a waste of time. I have probably logged close to 20 tickets or more which nobody has ever responded too, I have monthly subscriptions I'm paying and I have no benefit because it only works with internet, I'm just tired of this, all I want is my money back, I'm having to buy data and I've told this story before.
