Swagbucks Shop&Earn refusal of reimbursement Redondo Beach Internet

I had made several big purchases via the Swagbucks toolbar on Google Chrome. When I made my 3 purchases, which were in the same day within hours from each other, I had double checked every time to see that "Shop&Earn was activated" on my toolbar before proceeding to purchasing. I had a 30 day full return policy with the merchant. My first purchase via SB they were able to reimburse me for what was owed. My other two purchases were denied because of various reasons, apparently.

First it took SB over a month (~35 days) to inform me that they could not verify through vendor that my purchase was made from SB. When I continued to push the fact that THEIR toolbar showed that my "shop&earn" was activated, they forwarded me to a "User Compliance Manager" and she then found other reasons why my purchase was not valid. Main reason was that upon reviewing my receipt, it showed I had used a discount code and any discount codes not endorsed by Swagbucks would disqualify the purchase from receiving any SB points. She then referred me to a FAQ page that shows this rule.

When I pushed back that the FAQs is a non-binding rule and was not stated on their user agreement, she changed the story back to the system couldn't get verficiation info on my purchase and that SB was not paid by the vendor and thus they couldn't pay me. When I asked again what could be done in this situation since their toolbar did show my shop&earn to be activated, the manager changed her story yet again to my purchase not qualifying because the discount code that was used. Only this time, she pointed to the user agreement's "Additional Terms" as referring to FAQs. I believe there is a lot of shady practice here because the sum that they owe me for my 2 additional purchases is a few hundred USD. The User Agreement is way too vague to inferr any connection between the term "Additional Terms" and the term "FAQs page."
