I wanted to trial HiFi subscription for 30 days.I have changed the subscription from standard 9.99 to HiFi plan and i was immediately charged 19.99.I only paid my regular subscription of 9.99 on the 22/11 and on the 28/11 paid additional 19.99?I emailed twice deezer customer service demanding to refund me the money, but there is no answer.Very disappointing and thinking of moving to Qobuz soon if this is not resolved.
