Suburban Diagnostics — Sending patient back without carrying out investigation and demanding cash payment

I had booked online appointment for USG of my husband today at Suburban Diagnostic Borivali west centre above Tanishq. At the time of booking appointment I had clarified that I will make online or gpay payment. When my husband went for sonography at 6 pm the lady sitting at reception and one Mr Sachin Salunkhe( I got his number through true caller since my husband forgot his cell and called me from his number ) insisted on cash payment and didn't allow him to get USG done and sent him back. Such kind of treatment is done to patients who are already in pain and they have no courtesy. Serious action to be taken against them
