Omaxe — Car parking charged twice

Hi, I would like to take into your consideration that we were charged the omaxe mall car packing twice. Firstly we tried paytm. They deliberately said it was not working but it was. One 70rs was given cash and the other 70 was debited from our paytm account. What is this gimmick to. charge extra from customers? I can even provide you with a screenshot of online transfer, if you insist.
Very bad policy. Kindly provide me number of the executives with whom I can talk and get my money back
