I was able to get in touch with a representative from McAfee. I dialed 001-866-6223911 using my cellphone and was able to talk to Gel (I believe it is from a call-center based also in Manila).
It is better to talk to them since there is no way a bank can refund the transaction since it is a transaction between us and McAfee.
The person on the other end of the line was very nice and even offered me some promos should I wish to stay with McAfee. I told them I will decide later on.
I can now sleep soundly knowing I'll get back almost P8,000.00 I was charged.
God bless everyone!
