Bad service!!!

I have a contract with vodacom where I got an Alcatel link hub router with data. The router started having issues where it heats up and disconnect. I first called to report the issue, and I was advised to reset and all that nonsense, and the problem continued. I was then advised to send in the device to the nearest vodacom shop for repairs, which I did. I then took it to Lakeside mall, and I was not given a courtesy device. The device was sent in, and vodacom repairs credited lakeside mall for a replacement, and to my supprise, Lakeside mall don't have stock. So, I have to continue paying for the services I'm not getting. Vodacom please stop ****ming us. The incompetence of staff at lakeside mall is shocking. They don't even know how long will it take for the new device to be delivered when they place an order, wow! So I must just wait while the debit order is not waiting.
