I have a classic with CL 14k, expire in nov. Will the new gold upgrade keep the CL and renew it?

What i like about hsbc is the frequent cashback activities.

I got cash back rm50 this month statement too.

I have a problem with classic. Last month the payment due (auto pay with advance acc) is 13k. However at that time im overseas, and i need the CL to pay for hotel,car etc, so i manually transfer from my acc to cc as payment. i paid like 9k, left 4k left to pay. I thought the system will still take 4k from my acc, but it didnt. It shows "payment 13k" and "payment return 13k" so end up i kena a finance charge rm40. Can i argue it and get it waive? Rm40 i can go for a good dinner
