Lifecell International — every year someone from the company first sends a suspension notice and then has to follow it with a apology letter

I have been paying all my fee in time every year but every year someone from the company first sends a suspension notice and then has to follow it with a apology letter.
They claim of a cheque bounce but are unable to produce a cheque bounce memo from the bank without which my bank in writing has refused to accept.
Request the details of the grievance cell of lifecell so the this matter can be solved once and for all.

Regards,
