terrible call centre service

Ive been calling cell c to make payment arrangements the whole day with no answer... can you honestly tell me the call centre is so busy they can't answer any of my calls throughout the day??? i asked them to send me my statement via e-mail,it's been months later and i haven't received 1 statement to date and when they do answer your calls their consultants are not polite at all,not to mention the parties they have in the background while you trying to sort out your matters.
