Experiencing the worst customer service with Zando

I placed an order with Zando on the 13th of May and till today the order is not delivered and I sent them an emails requesting them to cancel it and Refund the payment. Every time Im told that the parcel is shipped to their courier company and I can only cancel it with the courier company WHEN they contact me. Its been over a month now and they are now not even responding to emails anymore , telephone lines are not working. I feel once they debit your account , they dont care anymore Worst costumer service
