Greedy Builders warehouse

I set up an online profile, received my account activation email and placed my first order for almost R9000. 5 days later, I received a new email with a welcome letter and 15% coupon for my first order, with discount capped at R1500.00. Now my first order had already been placed but not delivered, but I would qualify for about R1300 discount- if Builders has sent the coupon with my activation email. But they are sneaky by sending it so late. I went in store to the branch facilitating my order. They couldn’t help me because it was an online order. I spent several minutes on the phone to their call centre- which went unanswered. I was given an email address instead. I sent an email asking for my discount to be refunded onto my credit card. It took 5 days for me to receive feedback, when I should have been answered in 48 hours. The consultant said I couldn’t be refunded, but gave me a coupon for 15% off my next order. Why must I sacrifice such a considerable amount of discount when they deliberately take their time sending welcome mails? I think it’s disgusting that they pull these type of stunts. Since the items hadn’t been delivered, I requested that they cancel my order, but I’m yet to receive a response on that. Builders warehouse needs to be named and shamed for corporate greed... I’ll spend my hard earned money elsewhere. Mash-hoodah Allie Is the consultant handling my request
