Address:

Kolkata, West Bengal, 700060

Myself mrs. C. Bhattacharyya from kolkata.
I am having consumer no. S2476 with saaheb distributors' agency, ph. No.[protected]/1746, 360a upendranath banerjee road, kolkata 700060. Today morning i went to that office for submitting kyc. Because when i got message, that time i was out of station.
But really i am very upset for agency staff rana guha's behaviour. One of agency staff talked with me and processed my work but rana guha constantly disturbed and behaved with me so rudely.
I am the patient of high b. P. And nerve. So if agency staff behaved liked that, then may be people will fall sick. So please take necessery steps against him. I will be grateful to you.
Regards,
Mrs. C. Bhattacharyya
