Very dissatisfied

They advertised the kitchen sink that it was on sale and after purchasing and already paid and recieved order number that’s when they send an email the next morning that it was an error. I feel like they should’ve sent my order and fix the error. What happened to the price you see is the price you pay. To top it up they didn’t even bother to call me and apologise but they just refunded me just like that. Don’t bother buying from this store esp sale items otherwise they might just cancel your order just like that. Leroy merlin send me my order please. I wasn’t even greed I only purchased one which i wanted.
