[Resolved]  NIIT — Refusal to be provided in-voice

I bought a SCJP voucher for the amount of Rs.4850 from NIIT APTC Center.I gave the exam in Kolkata as I was transferred there.Now, I need a proper in-voice for the purpose of re-imbursement done by my employer TCS.
I requested Ms.Ananya Patnaik ,an employee of NIIT APTC Bhubaneswar Centre ,to send me this in-voice.I have been calling up Ms.Ananya and requesting her to send me the invoice since the past 2 weeks.
Only to be told that it will be sent soon.I had notified her that there is a minimum period after which the approval for re-imbursement becomes null and void.
Inspite of all this she took it with a lax attitude.She finally sent me screenshots of the invoice which are not accepted by my organisation.
I expected a proper in-voice.She could have just taken a one page print-out of the same,scanned it and sent it to me. That is not much to ask for.Instead she rudely asked me to collect it from Bhubaneswar if it was so urgent. This is highly unexpected from an organisation like yours and raises questions on how you treat your customers.
Can you ensure that i recieve the invoice as requested or I stand to loose all this money????
This is the content of a mail sent by her:
Hi,

Thanks for making NIIT understand the true meaning of " Invoice". The screen shots send to you depicts the official invoice, the Student ID, the receipt number along with the candidate's name and address. Moreover, it shows the name of the Vendor along with the price and date of puchase of the voucher. Precisely, it is the "screen shot " of the original Invoice-cum-receipt.

For your information, an invoce (that you are looking for) is a system generated hard copy and should be collected physically from the Prometric Testing Centre, as and when required by the candidate. The same is available with NIIT APTC Bhubaneswar Centre and can be collected, i[censored]rgently required.

Thanks and Regards
