Second case of ***** on Discovery Card with no response from Discovery

I have been trying to get action on a ***** case on my Discovery card for over 3 months. I have sent countless emails and posted a review on Hello Peter which simply got a private message response stating that they had not received my forms or information about the claim even although they have had several follow up mails resubmitting the claim. This is simply not acceptable. Several more weeks have gone by and I have not been refunded for the ********** purchases and neither have I had any reasonable response from Discovery. It seems to me that they are not interested in resolving this situation, preferring to focus on getting new clients than servicing existing clients properly. This is the second time this has happened with a Discovery credit card. I have never had ***** on any of my other cards and neither have I ever had such disinterest in a problem from any bank.
