Very bad client service

On 28 Nov 2015 I went to Telkom to open an account for a wifi router. The store was very busy and Andrew approached us saying if we complete the application with him he will send it to the office for completion instead of us having to wait in store. He gaurenteed that the application will take 5-7 working days and the device will be delivered to me. It is 30 December and I still dont have my device. I have checked up on my application twice and its not even on the system. This is very bad customer service and I will never do this process again.
