Poor service from business call centre

I just received a sms this morning 9th feb statint that i have not responded to an e mail sent to me last week. Needless to say that they used an incorrect email address. Now i spoke to business call centr last week and i gave them my Correct e mail address but it seems to no avail as they continue to use an incorrect address. I tried phoning them 6 times this morning but was cut off every time.. THIS TOTALLY UNACEPTIBLE AND NOT ON. If they dont call me to day by 11.30am i may move my insurance elsewhere.My contact number is ***. SHAME ON YOU AND WOULD QUALIFY FOR MAMPARA OF THE MONTH.
