• Flat: Service Tax and VAT overcharged / not paid to government

I have bought a flat in Bangalore (registered in November 2015). The developer has charged VAT ~ 2.5 Lakhs Service Tax ~ 3 Lakhs (mentioned in the costing spreadsheet shared by the developer via official e-mail). However he has not given me any receipts towards the same. A fellow resident who was also charged VAT and service tax inquired with authorities via RTI and got information that there is no VAT deposited by the Developer on that resident's name. Also there is a huge gap in total taxes that should be deposited (simple ballpark calculation) vs what is deposited. So it seems that there is something amiss. When I look at the costing spreadsheet it appears that I am overcharged on the taxes for example the developer has charged VAT and service tax on the deposits for Sewerage Board and Power Distribution company.

My questions:

1. Whether I can ask the developer to give me receipt for service tax ? whether the receipt can be used to track that the money reached the authorities ?

2. Whether the service tax and VAT submitted to government bodies are expected to have consumer name ?

3. In cases of wrong / overcharging can we claim reimbursement ? How does one establish overcharging/wrong charging ?Is there some manual from which we can say that particular item should not be taxed for VAT/Service Tax ?

4. How does a consumer get information from the authorities that the service tax collected by the consumer is deposited with the government ? please give some details on what information can be sought from the government to establish this ?

5. Are consumers entitled to a VAT receipt ? 

6. How does a consumer get information from the authorities that the VAT collected by the consumer is deposited with the government ? please give some details on what information can be sought from the government to establish this ?
