Damaged goods are an inconvenience

I bought a new Redmi phone at Clearwater 2 weeks ago, when I got home the screen protector is cracked and had no choice had to fit it like that. Few days later I was at Westgate so I thought I could go in and get help, only to be referred back by some guy at markham and even suggested I buy the screen protector myself since it costed R50. I don't have another money to travel to clearwater again. I was disappointed that I got that treatment, even wished the phone gave me problems so that I can return if and ask for my money back. The treatment I got was embarrassing as nobody took me serious, the markham guy told they can give me a screen protector and their customer will be short. My question is am I not a paying customer as well??? Well I'm not happy because the guy from Clearwater mishandled the screen protector and it cracked. So my phone might potentially crack because it's not sticking where it is cracked
