Bring back my damn money😡

A ****ty app ever😡 I don't when was the last time I took a ride with my card its been 3 months now every time when I have money in my account the damn app is deducting R30 on my account for what I don't know I've called and they tell me to call them with the registered number I mean what difference will it make... I just wanted to know why they keep on taking my R30 without my concern... Nxhaaa masepa
