Canara Bank — credit card visa debited wrongly

Address:

Bangalore, Karnataka, 560085

Credit card no. [protected]. On 21 9-2017 i have purchased medicines worth rs. 1017 and paid thru my credit card by swiping once. However, i got sms message over my mobile [protected] thrice about the purchase. I assume that it is banks system fault as similar instances occurred in the past several times. Please ensure that i will not be charged three times but only once. The message reads as follows quote dm-canbank rs 1017 spent on your cancard xxxxx5003 at mahaveer medical and on[protected] at 19:45:41 hrs unquote
