6 months, loss of Customers Belongings

After owning my phone for 2 weeks it no longer worked. I was advised to take it to Samsung instead of Vodacom as they were the specialists and would have it fixed sooner. When collecting my phone I was informed they had lost my box with manuals etc (2 March). I called and was never allowed through to their manager, always being told he would call back. 1 July I got hold of customer service whose response was just to email Chris Bolton, the supposed manager of the branch. There was a couple of emails exchanged where I thought it had be resolved that Chris would organise a box (to cover my warranty) to be returned to me. It is now 2 September and this is still not sorted. Neither Chris nor customer service has done anything about the situation. What HORRIBLE customer service. 6 Months and still NOTHING!!! I have wasted loads of airtime and my own personal time trying to sort out SAMSUNG's mess. What are you meant to do if both the manager and Customer service refuse to help a customer after losing their belongings??? I won't be buying a Samsung product again because of this poor service and will ensure that everyone I know is well informed of the poor service that comes with Samsung.
