Paid for 60 tablets only got 49

I called in yesterday morning on 26 June to check if my medication was ready for collection. The guy first check and said it looks like the right amount of tablets requested and they put it in a packet. And this didnt only happen at dischem. I urge everyone from now on double check in front of pharmacist that it is the right amount of tablets because i am short of 20 tablets. I paid for 60 but only got 40. Once at clicks i paid for 30 and only got 25. Either they are *****ing tablets or can't count.
