The price you see. Is the price you paying according to consumer right

Was at clicks dobsenville mall, on Wednesday When i felt very cheated n nt given the service a customer deserve.. Went to by mayogel and when i got ther it was marked at R14,50 surprisingly when i get to the till it scanes differently wit R26. 90 n i told the cashier thts not the price i saw n we went to the shelf to double chck indeed tht was R14. 50 i saw. The manager called mandlakazi gave me one hell of a debate arguing sayng the price i saw is for a small bottle bt no small bottle was packed ther n all i got was a very bad service from the manager and the cashier. I really dnt appreiciate the way i was treated i evn toke the picture of how it was packed... Such people dont derseve to be managers if they cant treat their customers wit the way i was treated i evn doubt il ever go to that clicks ever again... Il really appreciate if this can be dealt with before the store stop getting customers. Im so so disappointed that local stores treat customers with such bad attitude, worse frm the manager of the store. So disappointed i must say..
