Flink - my boss wants to endanger my life and puts pressure. What can I do?

Hi guys,

I work at the grocery delivery service called Flink.

Here everything is tracked from the time taken to deliver, to time spent at the customer, to time spent at collecting the groceries.

Now I work at Wuppertal which is a quiet hilly area. Most of the e-bikes are very bad, most customers are at 3-4 floor of the building and mostly there is no elevator that's why they get the groceries delivered.

So our boss alerts everyone who is taking 2 mins extra on delivery or have more then 3 mins of time spent at customers.

I'm pretty sure it takes more then 3 mins to ring the bell and go upstairs to 4th floor with bags of groceries and come downstairs.

Once my bike almost tipped backwards due to the load of groceries because it was total of 4 orders for 4 different people. I wrote a big message in the group telling condition of the bike and I was kicked out so my message could be removed automatically.

I really need a job at the moment and honestly I find it like I have to drive fast, deliver heavy groceries and the boss keeps notifying if there is 1 extra minute spent more than her expectation. I'm not sure even who to complain about this.
