"Temu offers free merchandise, if you download the app. There is no mention of previous purchases at the time, but there is later. So, you carry on. Afterwards , there is no mention of your free choices but there certainly is of the items you have paid for. Look into it and all sorts of obfuscations arise :the" rules"are quoted, mentioning doing things "at the right time" but when that is is not mentioned. The "event" is, mysteriously, no longer available when you enquire.I leave it to you to decide if you wish to deal with such a company."Overpoliteness, combined with total vacuity, are always a warning sign, I suppose.
