Airtel — unwanted notifications

at a time the best cellukar service provider now are on the path to achieve the worst services & customer help.
Since many days I regulary get sms from # 57333 - you have a new mail. Sub: Connexions alert: new mes.
And in the same manner another sms from #[protected] thanks for using alert services on Airtel sms.
The limit is I get such sms nera about 70 in a day as a result I loose my useful sms to read.
Many a times complained to helplinr officers but they are to care for bills & other unwanted talks on helpline instead of taking care to customer.
THIS IS ALL ABOUT AIRTEL - SOON GOING TO BE THE WORST
