Just to share my experience. Thanks for Bro sinafteh for directing me to this lobang.
I couldn't find any better offers online except the 6 MPBS recontract and recontracted with them via phone. That same night, I got wind of this 1 year contract 10 MBPS from Bro sinafteh. So I called them to cancel the 6 MBPS contract. It took a lot of time to finally get the message across but here's the main arguments I put forth.
1) My contract ends Apr 2011. So even if I cancel, I should not pay any penalties even though I cancel now as the new contract has not started.
2) Expressed extreme displeasure on why Singnet is so intransparent on the deals and offers and why it is so hush-hush.
3) Then threaten to TERMINATE the plan. Yes, unfortunately, this does seem to be the keyword....
4) The CSO from retention then called.... Interestingly, the first thing she asked me was, "May I know where did you find out about this offer?"...
Hopefully, this may help some people out there who are looking for a good deal or those who have a "fear" of calling them. And that you don't have to do step 1 and 2 like what I did... All in all, the whole thing took 3 days to finally close this issue.
However, if you have started a new contract, then I think it is more difficult...
With this offer plus bro sinafteh's offer on Starhub, I managed to save ~$50+ per month. Maybe we should put up a tracking number somewhere... Like how the coupons website always display $$$ saved etc... Haha...
