I have filed numerous complaints with customer service about Starbucks in my area (Covina, CA) frequently running out of ingredients for drinks a nd the issue does not get resolved. I have been promised a call from Regional Manager, but I receive no call back. The issue continues. Just this week I drove to my local Starbucks on Azusa in the city of Covina, CA, waited in long line only to be told when I arrived at the order screen that they ran out of soy milk, kiwi for star drink and coconut milk. I drove to two neighboring Starbucks only to be told the same thing. I am promised a call from the Regional Manager, which I never receive. So disappointed in Starbucks on how unreliable Starbucks has been in making sure customers get the drink they desire. I am so frustrated that I am getting ready to boycott Starbucks.
