Terrible after sales support from Zando

So disappointed in Zando. I can say that I will probably never use your services again! My order (***) arrived quite a few days after the scheduled timeframe (I can understand this might be due to the Christmas season but the lack of replies to my email in which I asked when it is expected, is something I am very annoyed with!). I then received my order and found out that the two pairs of shoes were a size too small. Last Tuesday (31/12) I emailed your so called customer support email address about exchanging them for a bigger size. I then followed up again on Friday (03/01) and have not had one response to either email! Your app and website login are also not allowing me to request a return/exchange (my order doesn’t reflect as a past order) so I am now sitting with two pairs of shoes that don’t fit me and no one who is assisting me.... so disgusted with your lack of service.... this has all been such a long and unnecessary hassle. Why have customer support if you can’t ‘support the customer’ with issues.
