Device not Repaired

I recently sent my device for repair. In fact the charger was not working and I had to send it both. They sent only the phone back without a charger, which then makes me wonder if quality control is done. I'm not even sure if the problem was attended. I had to wait for 3 weeks but after that I had to wait again for the completly MTN *********** but at the end of the month I have to pay for this kind of service.I sent 2 emails too their complaints department none of them was attended to,what type of a company fails to meet their own standards.The store (KLIPMED) was suppose to notify me for collection but that was not done I had to find out by self. This kind of service is total unacceptable
