They took my last cent and left me with a broken heart on my birthday month!!

Zando online shopping site has poor customer service, I ordered a few things from them weeks back and they sent me an email stating that my "order was not successful and they have not received any payment" yet my bank reported to me that Zando took the money from my account. So, I emailed them several times before they could respond to my emails. I sent them proof of payment from the bank, it's only then that they admitted that they received the payment and said that they will return my money within 72hours, I have been waiting for 2weeks now, they are not taking my calls nor responding to my emails. They took my last cent and left me with a broken heart!!
