Bad service

so i got my htc android phone from blc. But now i am still waiting for sim activation and some to come back to me to tel me why its taking so long. Still waiting for them to call me. This is really bad customer service. I have got my phone 17/11/23 and its now 21/11/23 and still no sim activation. So now i am counting 4 days. This company clearly doesnt care for theire customers not giving them the service they deserve. I see allot of complains of this company blc. Now i am really fed up waiting so long. I wonder if they going to keep up their end of the bargain in 2 years time if they cant activate my cell c sim card in 72 hours
