No Stock No Assistance

We are currently clients from Telkom, and we were very interested in the Explore and Internet deal that Telkom and Dstv had going on, when we contacted Telkom in the Vaal mall they told us that they had no stock and that they will receive stock the following Friday, they will order it for us and they already did our upgrade as well, Friday came nothing from Telkom as they promised to call, we went in to the branch where my husband was assisted by Fortanute, she told him that they still had no stock and that she will put an order in for us she also gave us her card to send her an email that following day as we did, we had not heard anything from them there was also no order made for us as she promised, we complaint with them and no one seems to assist us they just say there is no order pending, now tell me how is it possible that no one seems to know how to do their job correctly and why does no one want to assist us with this matter, it is very unprofessional, how can a currently Telkom customer not be assisted is that so much to ask, I want to know who is going to sort out this problem or should we just cancel our Telkom contract and go somewhere else.
