Yes but they don't recognize your appointment as we called in morning and informed.  May be they are not trained to understand what's appointment given by company and secondly who is samsung Note 9 customer. Very pathetic experience but still we tried by visit also around 2 pm where  we get reply to first take token between 10 to 12 then be in Q. If mobile is having a smallest problem it makes ones life disruption especially when it is used for business, banking etc as all in one. My one simple suggestion is ADEQUATE TRAINING TO CUSTOMERS CARE AND TREAT CUSTOMER IS ALWAYS RIGHT. MOREOVER PRICES OF PARTS , ACCESSORIES IF TO BE REPLACED SHOULD BE SUBSIDIZED AND NOT DOUBLE TRIPLE AS DONE. my phone got issue in last 10 days and in less than 2 year of purchase. Phone is not sturdy so easy to find faults with customer of moisture, fallen etc as preventive measures.

Tried with customer care with their pickup paid service as they assured FOC REPAIRS but later said it fails on water test do cant help. to pay 17500 with 3 months warranty. I amcwelk aware that this is IP68 COMPLIED WATER RESISTANT TEST. SO company have excuses, selectively they have allowed. in telegram there is big common group of world customers facing same issue fighting for this. company ignores customers who have paid high amount on purchase and no one checked whether it passes WATER test or what is IP68 COMPLIANT PHONE. VERY PATHETIC AND NO CUSYOMER FRIENDLY APPEOACH BUT LOOTING CUSTOMERS FIRST ON PURCHASE THEN ON PARTS
