Worst, most unprofessional pharmacy ever!

The worst, most unprofessional pharmacy ever. At least 3 times now that when I call and am unhappy about something they start yelling at me and deny any responsibility. The worst thing for me is that recently I told a call operator that I did not receive a call and no one told me I had no repeats left, after which she said they sent an sms which they did not, and she proceeded to yell at me for 10 minutes and tell me it is my responsibility. One call operator says my medication has been put through to the medical aid to be claimed, and when I called again they said the previous lady did not put the claim through. Deliveries are unreliable, one time they say it will take 48-72 hours, another time they say it will take 24-48 hours; one time they deliver within 12 hours, another time they deliver more than a week late. I had no medication and it had serious effects on me. Most of the time one or two of the medications they deliver, they deliver 2 or 3 packs of, which has an effect on my medical aid benefits. I have never had a consistent, good experience with them and have never dealt with such an unprofessional business in my life.
