Not able to re-order medication online and now its our problem, Wife is a type 1 diabetic so this is a massive issue

What's the point having medexpress if they refuse to help? My wife is a type 1 diabetic and uses insulin 5 times a day. We got the email to remind us to renew her medication, tried to do it but all of a sudden EVERYTHING is missing for re-order and checking order history we still had 2 repeats left of everything. So Medexpress and Discovery removed the prescription and inform us to load a new one, my wife made an appointment with an endocrinologist last year already and the earliest date she could get is late in April, so the medication that we SHOULD have gotten this month is nowhere to be found and not allowed to give it. SO HOW THE F must we load a new prescription if we are only able to see her DR in late April and by that time her medication will have been used up and YOU will most likely cause her to go into hospital for unstable blood sugar levels and this will cost you a lot more than given her the medication she needs. HOW is this OUR fault if we are not able to re-order her medication from your so called full proof system online???? if something happens to my wife due to you guys refusing her medication that is owed to her that she cannot get an earlier appointment you will have a much much harder situation on your hands than a hellopeter review.
