All our consultants are buy for two weeks!!!

I can't receive calls and I don't know why, I've been calling the customer service line but all their consultants are always busy...how can all your consultants be busy for two weeks at different times...how many times and how long am I supposed to wait until I get helped...If you don't have enough people hire more...This is totally unacceptable...you expect me to pay my bill every month even though I can't use my phone and have o way of getting help unless I go to one of ur walk in centre which also isn't a guarantee I will get assistance
