Almost every bank who has 1860 special support number also has a regular customer support number, you just have to check their website or your card backside to find that number.In my case, I also changed my number to a JIO number as it was getting expensive to reach their customer support team each time. I have raised a complaint to RBI, lets see now.
Btw, how much time did it took for you to get unblocked after the RBI complaint ?
You can call SBI Card support at +912239020202 from AVoID (Airtel and Vodafone) without paying ₹1/min.
