Complaint is raised last Saturday - 04/03/2023 still getting automated messages saying your issue will be addressed within 2 working days.

Pathetic customer service from Apollo Pharmacy. They asked to send the photos of product delivered and alternate phone numbers and they sent. They Acknowledged and not doing anything.

They are saying investigation is being done. What is the investigation they are doing here ...? Why do they need again these many days of time for this small replacement... So sluggish.. can't they resolve small issues within a day.. they deliver within a day.. and make mistakes and rectify them for weeks / months ... Do they think customers will come back on their app to buy again..
