mcAfee Purchased Product Online but unable to Download Product after numerous attempts Popondetta Northern

I purhased the antivirus called mcAfee Total Protection for USD$39.99 for 5 devices on mcAfees website. On its its landing page you will find the mcAfee Total Protection cost USD$44.99 for 1 year subscription. Howver if you hit the "Learn more" button you will be directed to a page where 3 discounted prices of the same product are sold for 1 year subscription, they cost;

1. USD$49.99 for 10 devices 

2. USD$39.99 for 5 devices

3. USD$34.99 for 1 device

I purchase the product online that cost USD$39.99 using my debit card thinking it was a good bargin. However after trying numerous times the product will not download on my PC. I tried the technical support but I was asked to download an app so that a technicain would access my computer to help me install the product which I refused.  The pre install Tool will not work and customer servie request number they provide is usless. I have tried to get a refund but they do not have a chat window or email address to help with the refund only a phone number to call if you want a refund. The call will be very expensive for me because I live outside of the US

The cheap price is a clear indcation that this is a scam to cheat genuine clients. Both the landing page product price  is USD$44.99 for  mcAfee Total protection and the discounted price for 10 devices are the same for 1 year subscription. You will notice that there is a little difference of  $10 and  $5 in price between the 3 products. I believe scammers have somehow attached malware onto the "Learn more" button and are taking money from unsuspecting customers or this is one way mcAfee is scheming people of  their money.
