Harmful to my health!

It's 3am and I can't sleep because I'm stressing about my high blood pressure medication that Clicks says they don't have in stock, last month they gave me less pills than I was supposed to get and this month the lady told me they don't have in stock and I must go back to my doctor for a different prescription!

Firstly, I cannot just take time off work anytime I please, secondly Doctor will charge my medical aid for any consultation that's why I asked to repeat prescription in the 1st place! This is not the 1st time this is happening and I don't buy the excuse that the pills have run out of stock from the supplier! Clicks is playing with the publics health and they don't seem to appreciate that without my medication I can collapse and die anytime. Does someone have to die before Clicks can make sure they stock medication especially for dangerous chronic illnesses???
