Blue label connect telcom nightmare

I took a cellphone contract with blue label connect last year,i lost my simcard in march this year,ever since that time till this day blue label has failed to replace my sim card and im still paying every month,i have been trying to get hold of them for months and when i finally got through last week they told me to buy a new simcard and contact them provide them with details of that sim,then they will contact me after they activate it.ive been waiting for them ever since,when i to contact them i eventually end up in line for more than 30min then they just hang up.im running out of ideas how to get this resolved... Blue label connect services are really a nightmare. I regret take this contract with them and wont advice anyone to take any services from them
