PharmEasy — Faulty cashback redemption policy

Cashback earned money is the property of customer.
Previously, the total cashback amount could be utilised in next purchase.
Now, you've restricted the redemption level by 5% value of next transaction, and this is simply ridiculous and regretted.
You will collect my money and keep it under your control, plus a nominal part will be available for utilisation and next cashback will be added to such an idle fund, which only accumulates, impossible to utilise except by a massive purchase, and that's not the proper way to procure medicines.
I strongly object this audacious policy handling the money of public by objectionable money mal-utilisation process.
You have no right to control usage of earned cash back amount, which is not your property.
I'm leaving PHARMEASY WITH NINETEEN FAMILY ACCOUNTS, And from Now on, I'll discourage and prevent my known people from using such a fiscally mismanaged medicine supply agent.
