"No communication."

Had face2 face appt at 13:40 today after filling online form in and receiving phone call back (all good so far). Attend appointment checked in online confirmed appt 13:40 all good. At 14:05 I approached desk to ask what happening with my appointment; I was told the doctor was running late but I was next to be called in. I was called in at 2:30 - doctor examined me agreed required a course of antibiotics & prescribed these. I left consulting room to find my phone battery had died which meant I had no way of paying for prescription (I know it’s my responsibility to have my phone charged/ a means of payment, my phone was on 17% when I left house after arriving back from airport so hadn’t had chance to charge).I believe if hadn’t been such delay in appointment battery would of held out. I explained this at reception & pharmacy, asking if anyone had I phone charger I could borrow (plug my phone into) for 5 mins to get enough charge to pay for prescription so I can get antibiotics. Apparently no reception or pharmacy staff at lion have an iPhone. I was then told I can raise concern or complaint regards the lack of communication in delayed appointment on webpage. However webpage states to complain it must be written complaint and instead advised these website to here to raise my concerns/feedback.
