Bad service and security risk.

My brother and I have been experiencing recurring google1 London purchases. Mine include HUAWEI recurring purchases. It makes these purchases when there is no money in our accounts resulting in bank charges for insufficient funds. And then at a later stage when our accounts receive money it deducts the charges incurred plus the purchase amount for whatever the subscription is for. Please note my brother doesn't have a phone or active subscriptions. Also I canceled my huawei subscriptions yet I'm still getting charged. Please do something.
