[Resolved]  Ylg India — Bill or invoice not given for services availed

Today I went to YLG Marathali near star bazaar.
We availed hair cutting services. First surprise was hair cutting was 950 plus taxes. After going for hair cut, the Stylist told that blow dry will be Rs 399 plus taxes extra which came as a shock as most parlors have blow dry in hair cutting.
After doing hair cut for me and my daughter. I paid full amount including taxes by paytm and got 20% discount.
I was not given the bill.
Cashier said printer not working. You will get sms. He told to take picture of the computer monitor which did not have GST number.
I did not get sms too. I went to other shops like Westside and came back to ylg and told cashier that I need GST invoice as I paid taxes.
He gave lame excuses.
I said without giving a bill the services are free and you should not charge me.
He said you will get bill on Tuesday on whatsapp.
I asked him why he is cheating. He said trust me. Also I never availed senior Stylist yet that was mentioned on computer monitor.
But how can I trust you?
You should give me bill for services I availed for Rs 3000 approx.
Isn't this cheating?

Please send me the bill by whatsapp or sms or email.

Else I will escalate it further.
