Unfairly Declined Well Deserved Payment

I recently received a booklet in the mail with my Players Reward Card that contains many RTG casinos' Free Spin bonus codes. For each casino listed in the booklet, it provides 3 different free spin bonus codes. On October 12, 2018, I redeemed bonus code PRCGEM at Planet 7 Casino which gave me 20 Free Spins on Gemtopia. After meeting the playthrough requirements, I submitted a withdrawal request for the maximum amount allowed: $100.00. I received an email stating the check withdrawal had been received and to contact customer support to see if documents are needed. Immediately, I contacted customer support and the agent stated my documents are complete and approved. Because I still had 2 free coupon codes (PRCCB2 and PRCAG) left in the booklet for Planet 7, I tried to redeem those and they were declined. It was no big deal to me because I had already won $100.00 and was looking forward to my winnings. After two weeks, I still had not received an email or check so I logged in to Planet 7 to review my account. Here is what was listed:

10/16/2018 09:27 AM Manager Withdrawal Approved! -$100.00
10/16/2018 09:27 AM Manager Withdrawal Requested -$100.00

10/12/2018 07:48 PM Coupon 'prccb2' requested
10/12/2018 07:47 PM Coupon declined
10/12/2018 07:47 PM Coupon 'prcag' requested

10/12/2018 12:07 PM Coupon Reversal Withdrawal Approved! -$168.14
10/12/2018 12:07 PM Coupon Reversal Withdrawal Requested -$168.14
10/12/2018 10:14 AM Coupon 'PRCGEM' redeemed $0.00
10/12/2018 10:14 AM Free Spin Deposit Approved! $12.00
10/12/2018 10:14 AM Free Spin Deposit Requested $12.00
10/12/2018 10:14 AM Coupon 'prcgem' requested

I contacted customer support because the last transaction states "Manager Withdrawal Approved" and I have not heard or received anything. Customer support tells me that my withdrawal had been declined because I'm not allowed to use multiple free chips in a row. I'm beyond outraged because I was only able to play with one free bonus code (PRCGEM), met the playthrough requirements, submitted my request, and now all I have received is a poor excuse from customer support as to why they're not paying me. The other 2 free spin bonus codes had been declined; therefore, there is no way that I could have used multiple chips in a row. I'm so upset because Planet 7 is wrong and if my withdrawal had been declined, why does my account indicate otherwise with the last transaction being "Manager Withdrawal Approved"? I know what I'm entitled to and would not be wasting my time if I knew that my winnings were not deserved.
