Dischem Klerksdorp Flamwood scolding me AGAIN for taking a few tablets at a time

I am really frustrated with Klerksdorp - Flamwood Dischem. This is the second time I have to complain about the same thing. I went to the pharmacy on Saturday to get my monthly tablets. Some of which I take a few during the month as and when mine is finished and depending on my financial matters. First the lady called Rosemary, told me that I was making things very difficult for them when I only take a few tablets at a time. Exactly the same thing a previous employee of Dischem told me - or more like scolded me. She had the audacity to even ask me why I was only taking a few tablets at a stage - which is none of her business. I then had to hear that I cannot get some of my tablets because I already got 30 of these whilst I take 60 a month. THUS because I took only 30 I not have to wait for it to be finished before I can get again and THEN they still only want to give me 30. My script is for 60 tablets for the month and am I not supposed to get 60 for the whole month? Now I have to go to Dischem every week and stand in the queue for hours just to get my tablets. Other pharmacies give the medication as it is prescribed in other words 60tablets for the total month in advance. I received 2 bloodpressure tablets 2days ago as I was short on this and then the lady will only give me another 28tablets. How does this make sense as I drank both tablets I had in the last 2days. In other words I need another 30tablets for the month - the 2tablets I received was not even in this month. Furthermore the lady told me I should bring all my pills to the pharmacy so that she can see what I have and then align my tablets accordingly - as if I am a child. I cannot make sense out of the fact that I cannot get the total prescribed dosis in the beginning of the month. It is a complete waste of my time to go to Dischem every week with some or other tablet being finished. I do not understand why I keep on getting the response that I make it difficult when taking part of my tablets at a time. Is it against some policy that I cannot do this? Is my business not important. After this happening more than a few times I am at the point where I do not even want to use Dischem again.
