Bad Shop Ever

After the poor service that I got from PG Glass Midrand they still need me to beg them for my refund, they made me to pay 100% upfront two days before their **** windscreen arrived at their shop and I did that by paying 100% with no hassle not knowing that they've ordered the **** windscreen for my vehicle. But now I've cancelled everything with them, but still struggling to get my money back...... as if im the one at fault. Why when I pay, I didn't give them a hard time... but why after their poor service that I got from a lady by the name of YONELA STORM am I struggling to get my refund??? PG Glass midrand doesn't care about their clients , even when they are at fault they will treat you like nothing. Now I need my refund but it seems like they are doing me a favour. They've damaged my windscreen while my car was at their shop, but they didn't even apologies to that.
