Zando returns a ****/item missing at pargo

The customer service at Zando is the worst. I order 2 pairs of boots, 2 different parcels were delivered. After fitting on the shoes they were extremely small and I tried to return it on the app. The app was not giving any Gauteng drop off locations , instead kept picking up Milnerton in Cape Town. I started a chat and was assisted by Francis M on the 10th of July. He sent me a link for the pargo drop off locations in Johannesburg and I told him that I want to return both pairs of boots. He said I must go drop off the boots and that is it. I asked if that is all and he said yes. The 2 parcels were dropped off at Tevo Retail Crossing and the next day a lady from the shop called to ask for the drop off code which I didn’t have and which Francis never logged or informed me about.. I started another chat on the Zando app and was assisted by Ann G who apologised and said the previous agent was supposed to request the code from Pargo to be sent to me when they processed the return. The query was escalated and I eventually got a code and called Tevo to give it to them. The lady asked if it’s only the 1 code and I said that’s all I was sent. I was not aware that I was supposed to be given 2 codes for each parcel but it was that. Pargo picked up the parcels and I was informed by Zando that one parcel is missing. They assumed that I don’t drop it off so I sent pictures of the parcels and how they were sealed. They escalated the query and a lady from Pargo called to ask if I really dropped it 2 parcels. I told her that sent the pictures to Zando and even the lady from Tevo confirmed it is 2 parcels. I don’t recall her name . The Pargo lady said she will get back to me. One parcel is now missing and this could have been avoided if the 1st agent did his/her job properly. The parcels went missing between Tevo and Pargo but it seems like they want to put the blame on me as the customer. I haven’t heard anything from them again and I lost certainly will never buy from them again. I bought the boots via pay flex and they are debiting my account for boots I retuned and never heard about again. This is really unacceptable and unprofessional. I want to know how the other pair of boots went missing and my refund processed.
