Aquapuratab review for SB: Helpdesk, Live Chat & FAQs

My store address is www.aquapurashop.com The first problem with the faq page is that on many desktops, laptops, mobiles, tabs, the drop down doesnt work no matter howmany times you click on a question. The second problem is that if we open 10 questions, we have to press back 10 times to go to the previous page. So it means that to go to the previous page, we have to hit the back button equivalent number of times as the number of Faq's we have clicked and opened.
