I have a question regarding how purchases are being charged. This is my first time using card market and I ordered 3 things from the same seller (it was professional selling with 2k+ orders) but after waiting for 20 days for my package to arrive ( estimated time was 10 days so I gave 10 days more) and I did contact him but he ignored me for almost 7 days now so I will open a ticket with CM and to ask for refund. My question is do I have right for refund in this situation and is the CM the one giving refund or the seller needs to approve. Any help is appreciated since it is my first experience with CM and I am thinking of switching to another platform like ebay.
