Disgusting quality from new Zando brand - Global

Zando used to maintain good quality products at fairly good prices. However, since they have introduced their new Global product range, quality seems to have gone right out the door! I saw the supplier was from China, but I thought I would give it a go anyway. I followed the sizing chart that Zando provides with the item and ordered the relevant size based on their guidelines - it measured the same as my sizing in SA. I received the item and firstly the picture vs the item received was not the same - the picture made the item out to be of better quality material than it is and the fit is completely different. Now bear in mind I am a size 8. My 14 yr old daughter loved the top, so I gave it to her and brushed it off to Zando providing the incorrect sizing chart with the advertised picture. That being said, the item that was delivered had no label or sizing on it anyway. I loved the advertised item so much, I thought I would give it a another go and I ordered 2 more of the same top (in 2 different colours) and I ordered size 12 thinking that perhaps the bigger size may fit like the advertised item. They are exactly the same size as the size 8, no labels, no sizing and the one top stitching is gaping so badly on the sleeve, there is a hole there.

I immediately emailed Zando and sent a photo of the damaged item as well as the detail regarding the sizing and poor quality. No response for days. I then called them and explained the situation and I refuse to pay the refund fee for something that is not my fault or within my control. Telephonically all goes well and the lady says she will log the return her side and not to worry.

Then I get an email stating that if I cannot prove that the sizing is wrong, they will not accept the refund and proceed to log a refund for 1 of the 3 items I ordered (the damaged item).

ARE YOU KIDDING ME!

The first top that is a size 8, that my daughter took ownership of, is out of the country with her for the next 2 months (she left on Sunday, I logged my disgust with Zando's lack of quality control on Friday).

I want my full refund for all 3 items! I do not see why I should accept substandard quality from a place who's brand has now been tarnished. Is anyone at Zando actually physically checking the garments from Global? I can buy better quality at Ackermans - on sale! And how am I supposed to prove the sizing that I received is the wrong size, when the item doesn't even come with a tag or label???

Zando needs to step up!
