SBI Credit Card — unnecessary finance charge

Address:

Indore, Madhya Pradesh, 452010

Sbi credit card is making us fool. They asked me to transfer 29000 on other card and there was some hidden tc* they have been charged me 4130 rs in last 3 months which is invalid. Whenever i transferred money and i got charged in next month i paid whole amount but the finance charges are still same. They are not refunding money now and making excuses. This is not the first time when they did this.. They have refunded earlier on my request but and there customer service is becoming worst and they are not responding. Please help me to get out of this cheat.
