False Discounts and Customer Feedback Censorship

I have recently noticed a fair amount of negative press regarding so-called discounts offered by Takealot and would like to comment as follows: 1) I always check the marketplace prior to purchasing anything on-line from Takealot (and others) and am selective in my purchases 2) If one takes into account their efficient on-line app. and delivery service it is sometimes worth the purchase - irrespective of the less than attractive 'discounts' on offer. A separate area of concern is what appears to be the deletion of less than complementary feedback on some of their products. Over the past few months I have been asked to give feedback on some recently purchased items and noticed that none of my comments have appeared in print. Am I just unlucky - or is this now becoming a (censorship) trend?
