Airtel — not respecting the customer

Address:

603202

I went to the airtel office in urapakkam, chennai to change my number from post paid to prepaid at 6 pm in the office. They said that you should come by 5. Even the reply was like they were replying to the beggar. Is this how the airtel guides to respect their customers? I know airtel offices are open till 7 pm in the evening. Then why are they not able to provide their services even when its not the closing time. I am really ashamed to be an airtel customer. I am the consumer of the service and they should treat their customers in the way they should. It is more than enough if they respect and value the customers. This is what we expect as a consumer.
