Dear Sir,
This is Subrajit, one of your post-paid customer at Delhi. My connection had activated on March 11, 2007 and as per the Billing Cycle is was closed on April 5, 2007.
But I’m sorry to saying that my credit limit is only Rs. 800.00, which is much less than my usage. Your goodoffice has decided the credit limit without verify my nature of job, designation, industry type etc.
So one thing is that, I am reaching to my credit limit within the first 15 days of your Billing cycle each month when I am unable to get in touch with my bills. Each month I would be facing the same problem that is disorder of service.
So, I’m requesting your good office to increase my credit limit atleast to Rs. 1500.00 in order to use your uninterrupted service around the month.
