Dell India — Laptop Inspiron 3511 - broken

I would like to add by horrible experience with Dell customer care . Would like to present my experience by point wise
1) Purchase Dell laptop in USA from Costco Site on Dec 16th 2021 which has basic warrantee for 1 Year.
2) Had some issue with Laptop and went to Dell service center.
3) Since the laptop is purchased in USA and Dell Service has requested to speak to Dell customer care on Friday. 4th March
4) Had called customer care on Saturday and they have requested to speak to Sales team for changing the tag to India instead o[censored]SA and you get it repaired with warrantee.
5) Since sales will not be working on Saturday and Sunday . I had called Sales and got the tag changes to India and it got changes on Tuesday .
6) Went to dell service center again and now they say since the tag is changed and you have basic warrant, you need to buy Premium support Pro.and ask them to speak to customer care again - This is on Tuesday .
7) called customer care and they said if you change the Owner ship which can be raised from Dell.com service will be done . Since i had very bad experience with Dell customer care on tag change, i had conference dell service center and Support team and after discussion between them .
Dell support said sorry sir, It cannot be serviced until you buy premium warrant and i need to get the laptop repaired with my own amount and then get buy warrantee .Surpise to know this because none of the customer service know how the process work and giving false advice .
8) I have asked for escalation point and support team said her manager will call in one hour and disconnected the call and i have not received any call .

I had an option of return the laptop in Costco with in 90 days and i would have return the laptop if i would have able to courier the laptop before march 16th . Due to customer support inefficient of providing wrong information, , i have wasted around 5 days and i cannot send it by courier as they will take 7-8 works days to reach which is not possible to send it my March 16th . i have to waste lot of money because of customer care inefficient . I have sent a mail to customer care and feed back email which they have referred is also not working, that shows how in efficient dell customer care is
