Kent — Kent electric glass kettle

I purchased Kent 16052 Electric Kettle 10 Aug 2020. But I regularly used this kettle before 2 months ago and after 2 months used kettle leaked from bottom side. Bill attached.
Please fix this issue as soon as possible.
Then after two-three days technician Naveen kumar, vasant Kunj service centre new delhi
(+[protected]come and check electric kettle and said that repairing not possible at on-site(my home) and kettle bring with me at service centre for minor repair and within two-three days kettle repaired and return by me. But after 3-4 days another person called(+[protected] and said that electric kettle glass broken and need to be changed and charged 700 Rs. What is the type of service of Kent. My kettle glass was completely ok when I'll gave on technician hand and also checked by technician before 2 days 02 times.. If Glass was broken, technician wrote in call voucher/service slip but glass was not broken and techinican said that he'll check at vasant kunj service centre. Please solve this issue.
