Worst Service i have ever experienced

My ADSL went down on the 31st of Sept so i called the call center on the 1st of Oct to inform them of this. the consultant assured me that it would be sorted ASAP. 3 days went by and no call or email at all so i called the call center, apparently the lady that initially assisted me "forgot" to log the incident... The new call center agent assured me once again that it has know been logged and that they will have it sorted. Called on the 6th and guess what.. call center agent says that no technician was assigned to my case. i demanded to speak to someone senior and after waiting for around 5 min on the call "he" came on the line. quickly started escalating and said that it will now be sorted. He also suggested that i go to any telkom store and ask for an integrated sim which is available free on my line. So i made my way to Telkom Centurion and guess what... No sim cards available. called Telkom again and started getting very IRATE. Tech finally comes out Yesterday 11th Oct (10 days later) and tells me that my modem is faulty and that i should take it to Telkom Reds mall and they will swop it out for me. Today i went to Reds and explained to the sales lady what has transpired and the first thing i get told is that this is not the correct process... so telkom themselves don't know what is happening in their own organization. She then says that they have no Tech's available and that i should drive again to Centurion mall as they have tech's available to test the appliance. Once again i drive all the way to Centurion and once i get their, The tech tests the modem and says that it is faulty. i then tell him that i have spoken to the tech that came to my house to test it initially and he says that if its faulty they will replace for me (Modem only 3 months old). The tech at Telkom Centurion then says that this is incorrect (again telkom staff not knowing what is happening in TELKOM) and says that they will fix it but would take 21 days. I told him that is fine as long as they can arrange the integrated sim. The tech says fine i will arrange, so i wait for him to get me a ticket for booking the modem in and arranging the sim. not even 2 min thereafter i get told that sorry all systems down and i must take my modem and come back. REALLY!!! 12 days waiting on Telkom driving from store to store and this is what i get told. Is this how telkom treats their customers??? This is by far the WORST service i have ever experienced. No wonder they are losing so many clients to other providers, who would ever have the patience for this kind of service. Truly shameful.
