Zando Jumia Trash

I placed an order with Zando in Sunday evening the 29/11. When I had entered my payment details & was waiting for the payment to get processed an error message was returned citing a technical glitch with Zando’s payment page. I then immediately contacted zando in all their platforms I.e. emails, socials. 2days later I received a voucher replacing the one that was saying used whereas the order had been recorded as cancelled due to unsuccessful payment. No consideration for the sale part, or time at which I placed my order & the discounts that were applicable, instead a voucher bearing ridiculous conditions of use! This is by far the worst customer service I have received from any 1 online store I have shopped with & shop I have during the Black Friday weekend. It is appalling to believe that this voucher meets any of my expectations in terms of resolving my query. Is it in any way my problem that you had system glitches when I was purchasing these items on Black Friday sale? My expectations of Zando in resolving this was that they’d open up my order as is/was saved on my app & allowing me to pay exactly what my total was, for exactly what I had in my order at the time of placing it (order no. ***). I have since unsubscribed from any Zando communiques, I have deleted my app & I WILL NEVER EVER AGAIN PURCHASE ANYTHING FROM THIS ZANDO CIRCUS! I will have to die before I make that mistake again. By the way, since Zando was acquired by “Jumia” or whatever, it belongs to the trashy league of online stores, just so you know! Stay far, far, far away from it, I sure am!
