Pathetic service and highest level of incompetence from takealot

I purchased a phone in August, order number ***4. Within a week or two of using the phone, it started malfunctioning. I returned it after a long struggle to back up my data and requested to be refunded. The refund was declined saying there's nothing wrong with the phone. I must be stupid I suppose. Now since September I have been fighting for them to deliver my phone and to this day I'm being told one story after the other. Can my phone be delivered before end of day, if not leave it and refund me. I'm sick and tired of this incompetence!!!! Every day it's a different story, who is responsible for ensuring customer items are dispatched and scheduled for delivery?????? This is utterly disgusting and infuriating on top of selling me a faulty phone and refusing to take ownership for it and refunding my money. Now I must fight for it to be delivered to me. And the customer number is useless as it drops all the time when you call. This service is pathetic and the worst ever. I am never buying anything electronic from them as they are vultures only interested in making money than providing a valuable service to their customers.
