Poor Customer Service

Trying to get through to a department that can help me to cancel contracts for my fathers death, but i cant get through to any department that can assist. I have been on the phone for over minutes and eventually dropped the call. this is pathetic service but to do a sale can the call centre direct you very fast to get through to the correct department that actually answers your call. This is really frustrating in a time like this for our family to actually cancel phones is very important. PLEASE CAN SOMEONE KINDLY ASSIST US!
