CCD — Forcefully adding "offer booklet" to bill having invalid offers

Address:

Bangalore, Karnataka

This incident happened at CCD, JPN Royal Plaza, Sampige Road, Malleshwaram branch.
A booklet of offers(Friendship Value) was added to my bill and given to me forcefully saying that the system is generating it and I have to take it and It's being given to the other customers as well. I resisted as I did not want any offer booklet but was given forcefully.
Since I got the booklet I thought of availing some offer related to movie ticket. Below the offer it was written " To avail of this offer SMS FUNCCD (CCD Invoice Number) to 57575 and get the offer code". However on sending the SMS each time I received the reply " You have entered an incorrect Bill No."
I contacted that same CCD branch and they kept telling me that they will get back to me after 2 mins and are trying to sort out the issue. They never called back and if I call they disconnect or start laughing . Ridiculous behavior on part of CCD staff. It's not about the money I paid extra or some hoax offer .It's about the way the staff behaved with me .
