Theme exchange option.

I had purchased before 4-5 days back a wordpress supermarket theme Oswad but it is very complecated and full with lot of problems. Purchaser is maximum depend on author for any small and normal changes for his website . I wish to exchange it with another wordpress theme .or refund my money…Plz. Suggest me the solution ?

Exchanges are not an option.

You can try and request a refund but the theme does need to be actually broken which from a power elite author and almost 5 star ranking seems unlikely.

Thanks !
