Debit card Debit message without any transaction

Received 25 messages within 25 minutes on 05.01.2019 time between 2.44pm to 3.08pm as – "Thank you for using SBI debit card no.559XX9307 for a purchase worth Rs. 249, 449, & many more on POS 248742000103177 at GOOGLE *PROXIMA BETA txn#491381, &GOOGLE *OCTRO Inc. &so on. though the POS is same for every transaction i.e 24872000103177. In this way after getting 25 messages of debit of Rs. 10000/- approx. from my card , i got a message that your card is blocked due to suspicious activities.
Since none of the transaction has been done by me therefore request you to look into the matter and do the needful for its revert.
