Disgusting and Dissatisfaction with new SP

At 4 month old my s5 was first booked in. It took a whole week before the device reached the repair centre. On investigation, it was revealed that the device had 4 faults, it was fixed within 4-5 promising weeks before it was returned back to the store. Not only did this repairing take 2 months of my contract time away from my, which I pay R450, the problem re-occurred. I once again have to await this long period before receiving my device, seeing myself in the same boat, as I am left once again without a device, which I am still paying for and I am guaranteed to experience these problems again. How does a brand new Samsung s5 handset experience so many complications in less than 9 months and the SP continue to not resolve the issue in a simpler manner. The store manager and escalation centre has not rep**** to my emails. I am left with a sim and no device and urgently require my device for business purpose. As a new customer I am receiving no service worth referring other friends and colleagues to telkom mobile. I want urgent assistance and no excuses!!!
