Product: Credit card or prepaid card

Problem Description : There were two charge of {$120.00} on my credit card account for a taxi ride which should have been less than {$5.00} dollar. I have called and reported to Citibank credit card and have opened the dispute. I have reached out to the company / taxi driver on the charge and they have claim it will be fixed. The charge was never corrected and I had ended up with two charges of {$120.00}. 

Once arrived back from a XXXX vacation, I have followed up the charge dispute along with request to get a new credit card cause i did not feel comfortable with such a fraudulent transaction. 

Initial dispute was filed on XX/XX/XXXX and another dispute was filed again on XX/XX/XXXX for both of the charges. 
XX/XX/XXXX XXXX XX/XX/XXXX XXXX I have contacted citibank repeatedly for the update and status of the investigation and the response was that it is currently being worked on. This process repeated through out the year even when I goto the dispute section it is showing conditional credit reversed and customer responsibility for both of the transaction. 

I have provided the documentation multiple times to the XXXX with the following references. 
XXXX XXXX Date Amount Description XX/XX/XXXX {$120.00} XXXX XXXX XXXX XXXX Transaction Date XX/XX/XXXX XXXX Amount {$120.00} XXXX XXXX XXXX Fast forward, XX/XX/XXXX I have received a very first response from Citibank with a response from the merchant. I wasn't clear on what I was looking at because it looked like transaction detail with the two charges. 

Also attached to the email was the first letter indicating that citibank needed a response from me by XX/XX/XXXX and no later than XX/XX/XXXX to continue the investigation. Which was a surprise cause I have called multiple times almost daily to follow up on the transactions due to lack of details. 

This experience has ruined my confidence in our banking system specially on credit card uses which I thought was more protected. The fraudulent transaction happen during my vacation at XXXX XXXX to take a short taxi ride back to my hotel. 
The way citibank has handled the entire process is very questionable, where I didn't know what was happening with the fraudulent transaction. 

I have spoken with numerous customer service and fraudulent department folks, whom failed to provide any details. As a consumer, only thing I can do is to refrain my self from using the credit card which doesn't make sense. I just hope these type of experiences don't happen to other consumer overseas..
