Builders Warehouse Online Shopping Falls Seriously Short

Placed an order 8 July for paint on their website. The order was split among 3 different stores, by 20 July I still hadn't received any parts of the now 3 separate orders, and requested a refund on the order. By 24 July, after numerous email follow-ups from myself, I had still only received a partial refund. On 3 August Jonnelle Siljeur advised that the balance of my refund was was partially credited to my bank account, and the balance of R224 credited to an online profile! I requested that the full amount be refunded to my bank account, and have not received further response since 4 Aug. Why would you partially credit a refund in such a bizarre manner. No one is getting back to me and this has been one of the most frustrating online shopping experiences I have ever had!
