Address:

maharastra

I have purchased a warranty from Lenovo Vantage on June 2021 and for that I paid the amount of 2149 INR. but still it is not updated, I also contacted the customer service many times since last 2 weeks but nothing happened instead they all behaved rudely and most importantly and I also received the Invoice copy of the warranty but lenovo is denying I have all the mail communication and also case number if required.

Case Number as provided by call center over phone : [protected]
here I am unable to attach the invoice copy and mail communication as only allowed format is jpeg hence I am attaching screen shot to it if any more details required feel free to contact :
