[Resolved]  HDFC Bank — HDFC Bank HDFC debit card EMI not working

I got 3.3 L pre-approval by sending sms from my registered mobile number - but when tried on merchant pos as shown on hdfc website - on pos machine it was showing as not available in base - what does it mean they told me that its card error - what does it mean - i tried to call on consumer loan customer care hdfc they were not responding fed up with customer care services so kindly help me out of this concern and let me know what is that not available in base.
I am struggling to get this issue resolved from last 6 hours talking to HDFC RM and Customer care but no outcome. HDFC is blaming Pine Labs and Pine Labs is saying its HDFC banks issue.

If someone frim HDFC bank is reading this then please try to resolve this issue. Both the merchant and I are frustrated now
