Dena Bank — to stop sms facilities and charges

I have contacted your dhrangadhra branch to stop sms facility in my saving a/c. No.[protected]. But it was informed me that to stop this facility the bank will also stop cheque book facility. For this i have to surrender cheque book and will not able to avail cheque book facility.
I wish to continue the cheque book facility. I only wish to stop sms facility as i do not wish to bear quarterly sms charges as i do not need sms for my transactions.
Kindly instruct your concern branch manager for the same.
