Reliance Communications Limited — Deduction of balance

Address:

192101

I am using the sim ([protected]) from just 2 to 4 months. In these months i am facing lot of difficulties especially in the deduction of balance. Before this complaint one complaint was already solved and i was assured that you will not face the same problem in future.
I recharged my No. with data as well as main balance. While accessing the internet I make a call to my friend but I was unable to do so as there was no balance in my phone. I checked my main balance and data balance. Main balance was 0.03 and Data balance was 10.00 MB. My balance was deducted and data balance remains there.
I have faced such problems many times before and every time Customer Care Executive told me that the system is busy or the link is down we cannot proceed your request at this time, please make call after 2 or 3 hours. When I call them after the said time again the same problem.
Please tell me what I have to do now.
Should my No. be discontinued for such reason.
