I hear you mate. I did do ok on my payback this month. Through contributing on the forum. Maybe you may want to do a little more of that if you can to maximise your income and chances.
I know exactly why my SR payment was so low. And that’s down to me. Just had a lot on and this tiredness doesn’t help. But it is getting better and hopefully this month I can get out and hit all my SIM card spots again as I know they are running low. I only see one or 2 pick ups a month now so all mine are gone so either replaced with others or bought and not used.
Hope it picks up for you mate.
