Debit order dispute no one has gotten back to me for a month!!!!

i called in about 7 times since the 24th of April to dispute a debit order on my account that went off on 24 April - i have been sent from pillar to post saying i am through to the wrong department yet PREMIER has their own contact number and additional services! i was promised that someone will log the dispute and call me back today is the 19th and i am currently on hold with debit orders as PREMIER cant do anything from their side!!!! i want this debit order to be reversed as no one can tell me what it is for!!!! ALSO tell me why I am being charged more for being a PREMIER MEMBER yet i see no benefits or "get helped faster" as you proclaim!! I DO NOT WANT TO SPEAK TO A BOT!!!!!!!!!!!!! I want someone to contact me and reverse this debit order ASAP!!!
