"Not the best for prescriptions "

I ordered items off my prescription 2 items I ordered were not processed by the prescription team,I received items I did not want of my prescription it is not the first time this has happened to me,I am careful to make sure I tick the items I want clearly but it does not seem to work. I underline all my prescriptions with I ruler to separate the said items I then tick the ones I need how they do not process them as I indicate I do not know,I ordered Novorapid 100 units I did not receive the item I ordered Jardiance I did not receive it, what I did get was co-codomol and a inhaler both of which I never ordered this is not the first time this has happened and I have sourced the two missing prescriptions from Pharmacy to u so can you please make sure my prescription is checked please before I receive it thank you Bernard Strong
