Ridiculious

I buy a contract phone on the 9 of June 2015. At first when i received the phone the sim card got stuck in it. So i phone them to replace the phone which they did without the sim card. So i phone customer care to send me a new sim card which i received up untill now. After waiting so long, i arranged for collection several times. The first arrangement was on 2 July and nothing happened till now. I phone week after week to collect the phone, but nothing happened. I so unhappy and frustated about the whole issue. All i want them to collect the phone but that didn't happened. What must i do with the phone if there is no simcard. Every week the customer service arrange and arrange and arrange. I just dont understand. I phone this morning again. Abd there they arrange again for pick up. I dont know what to do. This is poor poor poor. Such a big company with this type of service. Can you imagine. Please just help here, because im soooooo unhappy. Will not do any business with them in future. This is the last straw.
