Bad call centre service

Hi, I've been struggling to get hold of any agent that is capable and willing to assist with my request to amend cover before the next premium collection. Since once I'm transferred to the correct dept, three times these consultants who answer have cut my call or would not clearly state their own names. This has taken over an hour and wasted precious time and airtime and is leaving me very frustrated. Please arrange for someone willing to assist to give me a call asap or at least communicate with me via e-mail.
