Poor Service while unable to sign into app

My phone does not have Google services and the Capitec app used to work fine without it. All of sudden it is saying it needs Google services to run. I emailed *** and messaged with someone on Capitec's whatsapp service without any luck. I guess the annoying part is the no replying after the first email reply and the lack of willingness to find the issue from the Capitec whatsapp agent. How is this okay if Capitec's main drive is to get everyone doing their banking off the app?
