Hello, I just bought it and there is a mistake in the description. I is said it has bluetooth, but it does not. Can you please fix it ? It is otherwise a very good product, I will retake the same one but the bluetooth one instead of the 2.4. I am filling a return of the product since the description do not match but it asks me to pay CHF7 for the mail delivery. Is it possible to have the delivery accounted for in the refund ? Thanks,
