pathetic customer service from Zando

I bought the first pair of takkies order no:*** and were delivered on the 2 june which they turned to be small(not fitting) and i logged a return query on the 7th june 2020 since they were already out of stock and to this date i have not heard from Zando instead it says its pending.I then immediately bought the 2nd pair orde no: *** that looks similar to it which is one size up and now this time around the size is big and as i tried to exchange it from their website the option is greyed out.mind you i am angry and furious that both size 4 shoe and size 5 shoe are not fitting and i am fond with them,i then tried to engage with them via phone call they are not operating the sent over 4 emails and no respond and now i can to a point were i want nothing with Zando except for my money. the service i am receiving is pathetic to the core and no one is taking accountability or responsibility concerning this instead they send pathetic email messages about thanking Junad or something like that.I need yr assistance Just please help me get my money back i am done with them.
