EXASPERATED!!!!!!!!!!!!!!!!!!! and seriously disappointed by Diners Club card.

EXASPERATED!!!!!!!!!!!!!!!!!!! and seriously disappointed by Diners Club card does, not begin to explain my feeling right now!!!!! I used to be a proud Diners card account holder…. I was a loyal member since 1983. I have been trying to have my account sorted out and have been sending emails to several of their employees to no avail. I must state, however, that early in the process, some of the staff have been amazing in trying to assist me. However as the complaint when up the line, my experience is that they do not even have the courtesy of a reply. My latest email correspondence was sent on the 27th June 2019, and as of yet I have not had any response. This was addressed to a senior manager as well as their customer service department and cc'd to other employees who have assisted in the past. I have been trying to find the Managing Directors email address so that I can send him/her my email correspondence, so that I can get the matter sorted out and request an apology from them. Your kind assistance would be greatly appreciated.
