Apollo Pharmacy — Extra Amount charged online and delivery

Purchased thro their website according to online prices but when actual delivery happened self was asked to pay 190 INR extra . I paid the delivery executive as the time was already 22:00 I dint want him to stay late hrs due to their online fake propaganda and raised complaint with invoice and online proof etc ..
5 days over till now there is no feedback from their customer care but asking me to send same details of bills again and again which I did posted 3 times now . Worst customer care and unethical team out there.
