Chronic Medication not delivered

I called to order my husband's chronic meds on 2nd Nov 2015. I called again on 5th Nov 2015 as the meds had still not arrived. The pharmacist advised that they were out of stock of 15mg Cilift,and that was the reason that the meds had not been despatched. I advised the pharmacist to dispense 20mg and my husband could take 1 and a half tablets. He agreed and as my husband had run out of meds, he agreed to dispense and promised to fast track and deliver on 6th Nov . Nothing arrived on the 6th Nov and I called Medexpress once again. I was told that my husband could collect the meds at Dischem on 7th Novemnber but when we arrived at Dischem this morning they advised that the order had been cancelled. Fortunately Dischem gave us 3 days meds until this could be resolved. My husband is on chronic meds for the heart after suffering a heart attack and quadtriple bi-pass. He is also on meds after suffering a stroke as well as for hypertension. All of these are life threatening conditions and he did'nt have medication for 2 days. He started feeling very ill last night and had chest pains and palpatations as a result of not having meds.This is absolutely shocking.
