DHL TAKING ME FOR A RIDE WITH MY OWN MONEY

I was due to send out an item to USA but on the day shipment was due to leave i cancelled due to it was a ****. I called DHL and they stoped shipppment and next day gave me a form to fill for my refund. Amazingly i filled the refund form and sent it back. I call few hours later to check if they received it and Sue says nothing came so i say check your junk or spam, amazingly its there and she confirms receipt and tells me she will work on it soonest. I wait for 5 days and then decide to drop her an email. She then confirms its not done due to month end what what, which i dont understand. So i wait and drop email 2 days later and she tells me she has not worked on it due to being busy so i tell her how urgently i need my refund and she respond saying she will work on it. So i wait another 2 days and drop email again and she responds by telling me she needs POP. Why the hell did you not ask me that from day one?? I send the POPand remind her of the urgency of the funds due to commitmenrs. Then she dont reply and someone else drops me a mai (Randy)l and calls for POP I send it to them and call back asking me why they owe me.What the hell. No refund still. I need refund by 2day.danm u
