Vodafone India - Unable to use my Vi Balance

I had converted my PostPaid Vi number to Prepaid.
During this while clearing my postpaid bill, I had paid *** more as the store lady asked me to.
Then this got credited to my Vi Balance(ideally it should have been sent to my bank account).
Anyway, now the only plan close to *** I could use was ***(other plans are not working for me).
So I asked Vodafone what to do.
One person said recharge of **(you will get talk time of **) which gets credited to Vi Balance. Then the total will be *** and then you can recharge for *** using USSD.
I did that and after some call, my balance got deducted again to ***.
Then I was asked to recharge for ** again to get the balance to ***. I did that.
Now they tell me I cannot use this Vi Balance as USSD codes are not working.
In short, I am unable to use my Vi Balance. I am unable to use MY OWN MONEY.
This is a SCAM.
AT LEAST * different people from Vi have called me, and I had to explain the issue to EACH one of them separately. This has been so stressful I cannot explain.
My Concerns:
- Why am I not being allowed to use my own balance as I wish to?
- If USSD was not working, then why wasn't I told in advance? I was asked to recharge ** and **.
- When one complaint is registered, why does a DIFFERENT person call me everytime. I need to explain the issue to EACH person again and again.
- I was told wrong ussd codes by *-* agents and was asked to send screenshots.

HARRASEMENT!
