I decided to try delivering for Instacart to make a few extra dollars. At first everything worked out ok, but I wasn't impressed when I had to drive 15 miles each way to make a delivery for very little money. Still I was willing to do so. Several weeks ago, after completing an order ar Costco the app would not move past the part that I was supposed the receipt. That means I did not have the information of where to deliver the order. Both times I spent an additional half hour in the store in a chatroom trying to get help. The second time it happen I was informed I was not the only one that had this issue. Since I am a computer hobbiest of many years I know it was not me. The second time it happened it was so aggravating it caused me to lose their credit card. Finally the person on the other end just gave me the address and asked me to contact them in the chat room when I delivered it. They also ordered me a new credit card. The new card arrived yesterday, which was 2 weeks from when it happened. So today I took an order to Costco to deliver once again 15 miles from the store and my home. At the cashier it the app told me to use debit, but gave me no pin number. After holding up the line in the store, I was moved aside and spent 15 minutes in a chatroom once again. Finally I got a pin number. The manager took over and tried to help me complete the order. The pin number came back with the order declined. Further I was not able to get back to my batch to complete it in the app. Again in a chatroom for 20 minutes I was informed that due to a technical glitch my batch became unassigned. The person helping me in the chatroom talked a few things that made little sense, but assured me he would help. After 20 minutes I finally had enough, told him I quit, apologized to the manager for having to return the items and left the store. Now I have deleted the app and am finished with Instacart. If their app cannot work properly, and shoppers are dependent on the app to do so, I do not see why anyone would put up with that for such a pittance.
