Telkom and their pathetic service

On the 16th of December we went into their walk instore, completed a deal, we were told all products for the promo were not in store and would be notified when we would receive them. 2 weeks later we were called, most of the products arrived, just the router would be outstanding, and to top it off, we were promised a huawei wireless headset. We've been to the store more than once to query. Called several times, only for us to be told today, tomorrow etc. Today when we call, we are told it needs to be authorized by higher management as he wasnt supposed to release goods until he had everything with him. Who's fault is that? We have paid our installments done whats right and still no joy!!!! Telkom is this not considered *****? Regional manager refuses to even get back to us.
