Extremely bad customer service

I am very unhappy with the service I have received at one of your branch in Hebron mall, I purchased a rat repellent spray on 2026/04/30 and before I purchased the spray I asked the consultant by the name of Aluta more than once if the spray works before I could buy it and he advised and assured me that it works today I have returned the spray on 08/05/2026 as I was trying to return in the same person who sold it to me is refusing to take it back and while I was trying to explain that the spray is unsuitable and doesn't work the Manager by the name of Ludwig interrupted me and cut me off rudely with an attitude before he could even hear what I was saying, he told me he's not going to take that thing back, and I even ask the cashier to show me where on the slip does it say I cannot return the spray he just kept on telling me his not going to take it and ignoring me,I even told them I didn't use the spray but they kept on insisting that I used it asked for their branch manager's numbers and they still refused to give me.
