Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

Identity theft / Fraud / Embezzlement Ohio

I have a Lowe 's credit card issued by Synchrony Bank. I paid over and above my balance so that I could make a large purchase at the store. After my payment, my card had a credit balance of $2100.00 and a credit balance of $3600.00. My local Lowe 's store tried numerous times to run my card for about $5100.00 but it kept getting declined. Even when I called the credit card company and they said everything was okay.Finally I got a supervisor they then told me I could n't charge more then $2100.00 and I would have to charge it multiple times.The store would n't allow this. When I had a credit of $600.00 I would pay a cash payment at the store then I was able to buy products or charges over $600.00 without a problem.Now suddenly have a problem after they increased my limit. I called the credit department several times and was finally told that they would no longer allow me to charge over my credit limit even though I had a credit balance. I was told they would send me a refund check which I would have to cash and then take the cash back to the store. I have been trying to resolve this for over 6 days. The credit manager told me the check was sent - on -/-/16 but did not have the tracking number. I called back on -/-/16 because I did not get the refund. I am now being told the refund just went out today -/-/16 but still no tracking number is available and it will take over 4 days which means it will be over 2 weeks to get my money back and get my purchase taken care of.
