অসাধারণ সার্ভিস এই ইনফরমেশন সেন্টারের,বিশেষত তাদের ব্যাবহার অনেক সুন্দর। যারা অসুস্থ থাকেন তারা সর্বদা দুশ্চিন্তায় থাকেন। সে সময় যদি কেউ হাসি মুখে পাশে থাকেন তার থেকে আনন্দের বোধকরি কিছু হয় না। apollo information centre তেমনই একটি প্রতিষ্ঠান। তাছাড়া অনলাইনে ডাক্তরদের সাথে রোগী দেখানোর সময় তারা যে ভাবে সাহায্য করেন, নিজেরা প্যানেলে থেকে ভাষাগত ভাবে হেল্প করেন, বাস্তবিক সেটা প্রশংসার দাবিদার। বিশেষত ইসরাত জাহান আপু টেলিমেডিসিন পরিসেবা গ্রহণের সময় যে ভাবে হেল্প করেন,রোগীর প্রতিটি কথা ইংরেজিতে অনুবাদ করে ডাক্তারকে বলেন,আবার ডাক্তার সাহেবের কথা বাংলায় বুঝিয়ে দেন।সেটা এক কথায় অসাধারণ।তারপর, দ্রুত রোগীদের কাছে প্রেসকিপশন পাঠানোর ব্যাবস্থা করেন।এগুলা সম্পূর্ণ আন্তরিকতার পরিচয় বহন করে। আমি এই প্রতিষ্ঠানের সমৃদ্ধি কামনা করি।

It was a pleasant experience having interacted with Health Connect, more notably it’s representative Ms. Sunjida Sayed, in connection with my medical check-up at Apollo, Chennai Hospital. Her level of professionalism was outstanding, let alone the special touch of care in every bit of synergy. It means a lot to a patient looking for medical support.
