Tata 1mg — Medicine prescription issue

Address: Online

Website: 1mg.com

I am Care member of 1mg.com and buying prescribed medicines for my wife aged 67 since last one and half year. She is suffering from breath problem and on oxygen under supervision of the doctor. I do upload prescription on 1mg and place an order. Recently they started holding my order and call on my mobile and ask questions about the patient then they issue their own prescription. What is this practice?

Thanks.
