Not willing to honor the deal

Hi I needed to purchase something on the EBUCKS shop, and it's not allowing me to purchase. I called in to enquire but the service provider stated that I cannot purchase. The item I want to purchase is currently on a 30 percent discount. I require that fnd charge my account for the item and supply after the lockdown alternatively honour the 30 percent discount at a later stage. The team leader Phindiler had refused to assist.
