manager gave me bad attitude

I went there with my mom wanted to buy pap n gravy for my baby but the queue was very long then my mom asked if she could use the bathroom the lady in a red shirt answered to say no she can't s the store don't have water, I then asked for a direction to another place with toilet they said there's none then I asked to speak to the manager whom told me the shop had no water I can take it to care line if I want to. I expected him to apologize for the inconvenience and show a bit of humanity and caring for customers but he didn't. I reported the matter last weekend still waiting for feedback to date. I'm so disappointed with the manager
