Disgusted - Rude and Arrogant staff

I was a unfortunate customer at the Monte Casino branch of Candylious this Sunday. During my visit the staff were extremely rude and arrogant. I purchased an Ice Blast. On first tasting my Ice Blast I noticed that it did not taste like usual as I am a regular customer. I immediately informed the staff. They were extremely rude and refused to help me. When I asked for the manager I was informed that the manager is not there and they don’t have the number for the manager. They refused to refund me or give me another Ice Blast. They ignored my requests and told me they will not waste the product I must drink the one I was given. Absolutely disgusting behavior from a rude bunch of people who do not know how to treat customers. Disgusting!!!
