No marketing material, don't want to assist

I have two contracts at MTN (use to have more, but cancelled two of them due to lack of service, unattractive offerings)<br> I visited the MTN outlet in President Square, Krugersdorp. First of all I noticed that no one was eager to assist. ONE person was behind the counter helping a client, another was hanging products on display, another was fooling around behind the counter with something. There were no booklets or marketing material to inform me of the offerings available. I saw a SINGLE booklet. After waiting for 5 minutes I asked the person behind the counter, I think his name was Dave, if he had some of these booklets. He said it was his only booklet. I understand that they might be out of stock on these, but other than that no one was eager to assist me. Why should I beg for service? Why should I beg MTN to take my money??? I also laid a complaint about bad signaI at my home couple of months ago. No one ever gave feedback. Issue persists. I have approx. 26 active sim cards. Only 3 of those are MTN. seems like I have to reduce that figure even further.
