[Resolved]  Club Mahindra Holidays — Wrong accounting

I am a member of this holiday club from 2001 and have been paying my fees regularly. After 12 years the company comes to me with a pending claim of a pending instalment not recovered during my early payment schedule. This was explained as some accounting error in their system. Although i was hesitant i proceeded to pay because i didn't want to be claiming anything free of charge. However when i pay the amount it online it gets automatically transferred to my annual fees quota which is much lower than my pending payment. The company calls me to say the system again failed to park the funds in the right area of payment hence i need to pay the annual fees at the earliest failing which I may lose my membership. I have sufficient time to pay my annual fees but the staff is pressurising me to pay or lose membership due to their own system error. All this for their accounting error done so many years ago.
