Worst customer service by Markro customer care

My purchased item is okay, but I got the worst service. I sent an email immediately after I made the order to change my delivery address, my email was never responded to. So I called in a day later before my order was out for delivery, I spoke to a lady who confirmed that she will change my address. Later that day I got an SMS to say my order will be delivered to my old address, I immediately called in and demanded to speak to the manager or team leader. The gentleman that took my call said there's nothing he can do and it wasn't his fault that I sent an email to another Markro department, but wait I used the email that is on their website. I gave up and told him that I will cancel the order, he had no problem with that and said okay. The following day I got a call from the courier company and explained everything, they managed to reroute the parcel with ease and I got my delivery a day later. Markro online do not care about their customers or perhaps they are selective on who to go and extra mile for and who they just tell, there's nothing they can do. It's a pity but I doubt I will shop at Markro again, I will stick to your Game and Takealot because they are attentive and provide a much better shopper experience
