Frustrated by bad Customer Service

I am due and upgrade, and contacted Vodacom regarding this as my current plan is not catered to my needs and a contact with Telkom has a better offer, but as I have been with Vodacom for many years I asked if they could match the deal. This request was done almost 2 weeks ago with the service agent saying he would get back to me today I had to phone in again and the service agent made another excuse about why he had no feed back and that the inquiry was again reisssued to the next department. This kind of service really makes me wonder whether being loyal to Vodam is worth the effort as no effort is being made on their part to keep their current clients happy.
