Pick and Pay Fleurdal not keeping to their trading times

Pick and Pay Fleurdal Bloemfontein. Trading hours stipulated that they trade up until 19:00 on Sunday. I visited the store at 18:50 on Sunday 3rd of January and the store was already closed and after indicating to the security at the door that according to their time displayed that they should still be open they still refused access. Only after phoning the store and speaking to the floor manager, Grame, the doors was opened again for trading. This is not the first time that the store short closes before the indicated teading time. This is VERY poor customer service. KEEP TO YOUR TRADING TIMES, or rather change your trading times.
