What more do I need to do ???

For weeks now I have been sending ********** emails informing them about my change of email address. However they continue to use mt old emails for corresponding with me. After three phone calls (ay my cost) this week, I eventually got someone to change it whilst I was “holding on”. I then sent them a notification together with all the required documents relating to an investment maturing, requesting them to acknowledge receipt as well as letting me know whether there are any further documents required, so that this “transaction” can go ahead without any “hiccups”. Unfortunately true to form the call centre doesn’t respond to emails, both Twitter and Facebook messages are ignored. Considering that we the “Clients” pay for these so called “Consultants’ salaries, can you of them that wishes to earn their “daily bread” please contact me to resolve this “tedious matter”?
