Poor customer services and no product delivered

At the end of January 2018 I went to Telkom Blueroute in Cape Town to open a new cellphone contract. I filled out all the necessary documents. The phone I wanted, the new Samsung A3 was out of stock, so they had to order it for me. When I asked how long before I can expect it, I was told that the phone should arrive within a week of two. I was happy with the service I received. I patiently waited, about 3 weeks passed and I hadn't hear from them at all. I then went in to the shop and was told that no new stock had arrived. Then, after not hearing anything from them as to why my phone is not there yet, I went in to the shop again about 2 weeks later. A consultant told me that the store is over their budget and thus can't receive any new stock and this is why my phone wasn't there yet. He mentioned that I can take my documents to another store to start the process there, but I said I choose not to, as I this isn't convenient for me. Since then I haven't heard from them at all, and during this whole time I have not once received a phone call, message or email and yet they have all my details on the form I filled out. It is now almost the end of March, almost 8 weeks after I filled out the documentation and still no news from them. This is below average, pathetic service. More than three of my family members are Telkom clients and highly recommended me to switch from my current service provider to Telkom, I am now however doubting if this is the right thing to do. I would appreciate it if someone at Telkom could please let me know what is going on and why I haven't received any communication from them yet.
