Promotional Codes a ****

I received a Takealot advert on my Facebook Wall. It advertised a discount code that could be used with your first app. purchase if you installed the phone app. for the first time. I followed the link supp**** and installed the app. and proceeded to add items to my basket and checkout, upon which my code didn't work. I reported it to Takealot to which I was first told the promo ended end August. Then when I complained about being spammed with old adverts on Facebook, I was told they were mistaken and the code is still valid. Several e-mails later and this issue is still not resolved. It's the customer service level from Takealot that saw me take my business to another online shop more than a year ago. Please Takealot, come back to me with a solution. To answer all questions. Yes, I'm using the app to make the purchase. Yes, it is the first time I'm attempting to use the code. And Yes, I am adhering to the minimum spend as stipulated in the advert.
