Ideas on how to scam/annoy a scammer.

So may tumawag sakin kanina na taga BDO Credit Card Dept. daw sya at may 10k na points daw ako na mag e-expire today so nanghihingi ng details. Eh nasa meeting ako kanina so hindi ko napag tuunan ng oras (I did not give any info, of course). Sabi ko tumawag ulit sya mamaya.

Tumatawag na sya actually. So tinext ko sya at yan ang convo.

Give me ideas on how to play with this fcker. Thanks.
