Bark.com refund ****/*****

Can i give a rating of 0? Im going to try make a very long story short. I bought credits and got leads but nothing ever came from it. Then Bark decided to auto top up my account and deducted money from it yet again. Which is totally unauthorized. After requesting a refund they told me that the refund has been made. I waited for the 5-10business days for my money to reflect but nothing happened. I then emailed and phoned and they just kept telling me i have to contact my bank which i proceeded to do. My bank then said that no international payment was made, and that they need a proof of payment. I then went back to the emails and phone calls to bark where they ended up emailing which looks like a screenshot of a “payment/refund” that has been made. I sent it to my bank and they said that it is not a legit proof of payment and i need to contact them again. Bark just kept telling me that i have a invoice on my app and that i can use that. After telling then MULTIPLE times that a screenshot/ invoice is not a legitimate proof of payment they kept sending a generic reply saying i have to contact my bank. I am furious! How can a company like Bark not be able to send a proof of payment? Clearly payment has NOT been made and this is a TOTAL ****. Is there anyone who has gone through the same ordeal? That managed to get through to someone? I am so so so exhausted trying to get my money back and i am upset that i am now being ignored completely. I have now managed to speak to my banks ***** department and they are also now sending me emails about the format of proof of payment i need to receive? But how can i possibly get it if no one is willing to send me the correct proof?
