No Stock, No Feedback, No Response from Telkom Mobile

On 11th May 2018, I went to the Telkom Mobile Store at CityView Shopping Centre in Durban. I signed up to get the Huawei Mate 10Pro for R650pm. I was asked what color I wanted. I confirmed I wanted the grey. I was told they only had gold available at the shop and will need to order grey for me which will take a week to get it. Its been more than a week and still no phone. They do not answer their phones when I call nor do they respond to emails. I have to physically go to the store to get some sort of answer. Only to be told, they have not received their stock. My question to Telkom is, why advertise a product when you dont have stock? How much longer do I have to wait?
