Bad customer services and delivery on product

In September 2017 we went to menlyn mall - telkom mobile shop to renew my cellphone contract. I chose a package for a huawei p10 plus and you get a fitbit with. However they did not have stock of the watch and expected delivery in 3 days. They said they would phone. One week later, no phone calls, we called to enquire about the watch. They were still waiting for stock. So begin an endless battle of phoning, going to the store and still no watch to date!!! In November they didn't know anything about the watch, then they made a note. In December we went to the shop, spoke to the manager and it was again waiting for stock. It's been 4 months now, endless struggles and fighting!! Noone seems to know what is going on in the shop and phoning them is a nightmare as they rarely answer! Telkom please provide me with the watch before end of this week or I will take this further!
