Product: Credit card or prepaid card

I was promised a credit to my Chase credit card from a CSR at XXXX XXXX. I never got this credit. I did call back several times. So, then I asked Chase to deny these charges. Chase took a long time, then refused without investigating. 

I bought shellac and a paint roller from XXXX XXXX and had them delivered. During the online order process the XXXX site offered me a XXXX $ discount if I applied for a XXXX credit card, so I did that and I was approved. Then the discount was not applied to my order. When received the 1 gallon can Shellac sealer was very old, and very banged up. I have pictures. It was also not mixed. I mixed it and since it was so old it was so very settled that it literally took several hours for me to mix it. I poured some into paint tray and rolled it on walls. When I poured more out I noticed that there was a layer of thick shellac stuck to the walls of the can. I had scrapped and mixed all the settled from the bottom, but there was more on the walls. This shellac was bad. Additionally, the paint roller was not the brand that I ordered. 

I called XXXX  and spent over 2 hours on hold and transferred several times. I was told that the shellac should have been mixed before shipping, that they will send me another gallon and another roller no charge and that I'd get a XXXX $ credit to my credit card. She then patched me thru to the store which took another hour of my time. Then after waiting several more hours, I looked online and saw that the order was not placed. My project was already now behind schedule and I didn't have time to wait. So, I placed another order and called back. After about 30 minutes on hold, I hung up. 

I tried to call back several more times. 

The second can of shellac was also banged up and not mixed. However, I was able to mix and use it. The second roller came without the plastic package and it was very dirty. 

I was billed XXXX $ for each order. The first order should have been discounted by XXXX . The second order should have been no charge. Leaving me with a XXXX $ bill. Considering the trouble that I've had to go thru I'd like an additional XXXX $ discount. Meaning no charge for either order. 

I sent above to Chase within a few days of receiving the second order. After some time, Chase sent me an email telling me to read a " notice '' on their site. I've used their online complaint system before, but now it was redesigned and requires much more clicking and navigating. I could not find this " notice ''. So, I sent them another secure message and told them so. Then several weeks later they denied my claim. While on my account online I looked again and this time that " notice '' that they originally told me about was there and it directed me to fill out a form so they could investigate my claim. I sent another secure messaged, indicating that I was not able to find the form previously and that I did notify them of that and that I never heard back, but still they denied me. I said I'd like to submit the form and would like their decision to be reconsidered. They denied me again. Then I asked for a copy of all the records and information that they used to consider my request. They denied me again and said : " Mailed you a letter and asked for information about the dispute ( s ). Reviewed the information available.
