Very poor service from customer help line

I contacted your help line yesterday as i needed assistance to increase my credit card limit. As your app had issues. I spoke to Aziz Shaaista and we were on the phone for 37 minutes! Then i was told to hold on and kept holding for another 5 minutes with no reply from her side. I called back and asked the gentleman to speak to Aziz and he said she would call me right back. I am still waiting. I probably shouldn't have phone so close the closing team hence she didn't care to phone back. If this us how you treat your loyal customers then please terminate all my stuff with you and I will approach a bank that truly cares!
