I am facing problem with SBI Credit cards who are charging bill after they received the chq. payment stating after 5 months the chq. was bounced, whereas when i checked up with my bankers i.e SBI, they are confirming that the chq. was credited SBI cards on the same date and they issued certificate for the same which I forwarded to SBI cards but still they are not accepting and they are charging the bill alongwith fine / interest since 2 years which now became 5 times more. FYI, I have closed my card account with SBi after paying all my actual dues. But still they are sending statement charging fine/interest.In this connection I would request your suggestion to solve the issue as i am unable to tolerate their harrasement, regularly calling and disturbing during my working hours.
