No stock

I have a prescription for chronic medication. Doe the past 5 repeats there has been stock but Cozaar was out of stock for the last repeat. I had to go to the shop again for this . I do not live in Rustenburg, The shop is Dischem waterfall mall. 3 months ago a saleslady gave me Arthaway Osteo 1 a day capsules to buy instead of the tablets. Last week the store said no stock in warehouse, yet Greystone dischem has stock. Useless pharmacy
