Maizeys plastics bad customer service

I am highly dissapointed with the service at maizeys plastics in vereeniging. I went there to purchase a plastic sheet. I went and measured the size i need told the guy at the counter that i want the plastic sheet to be cut. 1 meter 20 centimeters by 50 centimeters. He dod the invoice and i paid. I went to the side where they cut it and left to go do buainesa by another place. On myreturn i saw thatthe zplastic sheetwas to amaal andwas measured as 1020 by 500. Went inside to the sameguy who assisted me he told my pay extra for a bigger sheet as i told him from the strt and i have no problem to pay the extra. But then he said he will speak to his manager to find out if he can do a refund on the old plstic sheet. And the manager said they must charge me a handling fee for something that was not my fault. I was highly disgusted when asked to pay a handlng fee for something that was not my fault. This shop does not have any decensy towarss their customers and blame their mistakes on the customer juat to make money. Highly offended in this shop
