Dishonest customer care

On 24 April I have placed a online order for two jackets from cape union mart . I was informed and undestood that the items would be delivered after lockdown I didnt have a problem and was patient .on level 4 lockdown i was informed via email that there is backlogg and delivery could take 3 weeks again i was patient . after 3 weeks only one jacket was delivered with no explanation . I contacted them via email and there repsponse was the is no online stock and they could not source stock from a store and they cancel the order and want to give a refund . I responed and did my own investigation and called cavendish store and Babsie from that store informed me they have stock and they have the size . I again tried to order the item online and it shows they have stock . I do not want a refund I want the item that was on sale for 30 % off . I request the discount should be honoured . Please have a look at this I feel they dont want to honour the sale product kind regards Eugene Nel
