Pathetic service agents

I have had the worse experience with MTN in a month's time. I have ordered one of their home internet and the modem got faulty and I was advised to take it the nearest store. The store took the modem and I was provided with e ref number which no MTN department gets to deal with, this was on the 13th of June and till today no one at MTN seems to know what department will assist me with my query. I have spoken with Ruth on the 17 who seemed to know what she was doing and advised of a 5 days turnaround time and nothing has been done. Spoken to Sive, Lethu, Thembakazi, Bathandwa, Nosipho - who was just not even willing to take that call as she pretended to not hera me and I spoke with one guy who also said he could not hear me until I vented on his silence and he later told me he can hear me. I spoke to a very rude agent who had me on hold as soon as she got the call and came back after 3 minutes and asked for my ID number and when I asked her why she had me on hold she gave me so much attitude that she is not supposed to tell me about what she is doing behind. This was the first and the last time I took out one of your products and I will let everyone around me not to get anything from you guys as your Customer service agents are so pathetic with no human connection.
