WORST SERVICE EVER!!!!!!

My order was delayed for three weeks after payment , i've called the contact centre a number of times and got nothing but bad service. Specifically Thoko who was the worst consultant i ever spoke to, as she refused to put me through to her supervisor / team leader, as i wanted to lay a complaint about my order. Thoko told me : \Ms customer i will not allow you to speak to my supervisor as there is nothing wrong i have said to you."She was persistant with not calling her supervisor "
