BEWARE!!!

BEWARE!!!

Do not. I repeat. DO NOT subscribe. They are not transparent with their business practices. They claim you can do a $0.50 trial. I tried it and cancelled it immediately after. Then 7 days later I get an unauthorized charge of $29.99 on my account! This is fraudulent activity and they definitely need to be looked into.

Hidden monthly charges

I took an online IQ test that popped up on Facebook. After going through the entire test it said that I had to pay $1.00 for the results. They said that my IQ is 129 but it must be much lower because I fell for their scam. Today I had a $19.99 charge on my account. I tried to get a refund but they said that I agreed to some terms or something. I never saw anything on my phone that asked for my approval to charge $19.99 per month to my account. Their site is no where near worth that much per month.

It's a scam

It's a scam. After paying the fee there was a $29.99 charge for NO reason. I tried to cancel and the website would not work. It just kept asking me to make sure I entered the right email address. I know I entered the right email address because I went to the website to cancel the charge through the email cerebrum had sent me.
Terrible service.
I'll most likely have to cancel my card.

Edit; 13 hours later and there is no sign of activity from this company after promising a refund. More sketchy behaviour.

This company owns MyIQ which is an absolute scam. If you pay the small charge for a test they will sneak in a subscription for $44.99 with no way to cancel it. Dirty dealings, paid reviews, a resolution crew that talks in circles and no refunds.
Reporting to the BBB and other consumer agencies. Not going to give me back my money? I'll make sure your scam is blasted all over the internet and consumer agencies to drive you out of business. This is Canada, they protect consumers here.

I have 8 emails that all say the same thing. “We empathize with the situation and need your bank account information to cancel your subscription “. I can’t go to the website to cancel as the website says I don’t have an account! HORRIBLE company. WORSE customer service

Cerebra IQ deducted money on my gcash

Hi Cerebra IQ,

I remember that recently I tried your 1-peso trial, but I was surprised to see that 188 pesos was automatically deducted from my GCash account. I wasn't aware that it would auto-renew or charge me that amount. I would like to request a refund as I didn't consent to this charge. I also sent you an email but still no response. Please look into this matter and process my refund.
