I am sorry to say that I love JetBlue but will discontinue my credit card because of the Barclays customer service. I disputed a charge that was delivered to the wrong address. I notified the company over 30 days of moving 3 times and they still delivered to the old address. The co. Then sent in a proof of delivery even though I told them the situation. The then called me but never left a message. Since I do not pick up un identified calls they closed the case. I then tried to call but was told I could not speak to a supervisor & I had to fax or email my complaint. Really…I spend over $200,000 a year and this is what I get. Good byeBarclays …no excuse for such Customer service or lack of.
