Lenovo — against authorized lenovo service centre in bareilly up

Address:

Bareilly, Uttar Pradesh, 243122

Dear sir,
I am... Ph. D. Scholar... Purchased lenovo... On date... (Please find invoice in attachment)

Last week, i had a problem with the touch screen of bottom buttons. I went to the service center - shivi enterprises, near patel chowk, bareilly, u. P. My phone has... Year guaranty. But still, they asked 3000 rupees for repairing in spite of many requests. Being your customer for many years, this is not expected from an esteemed company like you.
Please clarify me whether guaranty period does not cover repair charges and also please let me know so called terms and conditions for guaranty period.
Expecting you will maintain your customer friendly company promise.

Waiting reply from your side.
