Product: Credit card or prepaid card

Summary : XX/XX/XXXX - Granite was to be purchased and fabricated by XXXX XXXXXXXX XXXX  estimate was for {$5400.00} which included a 4 '' backsplash and a full height backsplash there was a sink included, which I did not need as I had purchased a sink ahead of time so XXXX would have to measure the sink cutout for the under mount and in our discussions a windowsill was added. 

Deposit was run on my Chase Saphire credit card for XXXX on XX/XX/XXXX Granite was installed and final payment was run on the same Chase Sapphire Credit Card for {$2300.00} on XX/XX/XXXX. 

After reviewing XXXX 's work there were issues with the installation of the sink and XXXX told my contractor there was nothing that could be done to correct the issue and he was done and he was not going to correct. I worked with my contractor to get the sink to at least look ok, but XXXX stated there was nothing else he was going to do. 

XXXX I balanced the payment with the invoice and discovered the over charge. 
I texted XXXX and gave him my accounting of the issue and ask for the money to be refunded - I did not hear back from XXXX, two weeks later I disputed the charges with Chase and by my calculation there was a {$1600.00} over charge on my account. Chase immediately credited my account for the {$1600.00}. I immediately heard from XXXX XXXXXXXX XXXX after the charge back hit his account and all of a sudden a invoice dated XX/XX/XXXX appeared with a different total. I received a letter from Chase on XX/XX/XXXX confirming the dispute that XXXX XXXX had 2 billing cycles to dispute the charges. 

I received a letter in early XXXX dated XX/XX/XXXX stating that the charges were valid and that I would have to re-dispute the dispute. I faxed all of my documentation to Chase as instructed on XX/XX/XXXX at XXXXXXXX XXXX at the branch on XXXX and XXXX. I recalculated the the difference using the new invoice dated XX/XX/XXXX and came up with a corrected credit that I was owed of {$1100.00}, I attached an explanation, copies of texts ( including a text from XXXX XXXX stating that he owes me a credit ) and was told by Chase they had 30 days to re-evaluate. 

I received a letter dated XX/XX/XXXX stating that my my transactions disputed are valid, however too much time had passed and XXXX XXXX XXXX refused to refund the money. 

As you can imagine this is NOT ok, either Chase Bank or XXXX ( XXXX XXXX company ) needs to refund this {$1100.00}. Chase told me this was not their problem and that I can redispute this but would have to mail them a new dispute. I spoke to a Supervisor by the name of XXXX at Chase Dispute department who tried to tell me differently and that there was no one else I could talk to and that I would have to send in another dispute to the same address. 

As a consumer what am I to do? Chase never called to clarify or ask if the information from XXXX was valid, they took exactly 30 days for the re-dispute which I find peculiar, they did not seem to think that a text from XXXX XXXX XXXX stating that he owed me money was valid nor did they contact me once in writing or by telephone to verify any information. 

Please advise on what I'm to do as I feel that Chase, who can not provide me with a name to talk to or an email, only an address I already have to send in yet another dispute.
