Call center is bad

I'm so livid with the customer service when phoning in...I received my new Fibre router but I'm having troubshooting on the device..so I contacted my ISP but they told me I should contact Telkom..so I called in and let me say who ever is behind the call center ideas needs to get fired ASAP, that idea of "sorry this is the wrong department please dial this number 08....etc" is totally stupid...I've spoken to 6 different consultants on my issue and they keep saying you in the wrong department call this number (the one they provided) IL be honest and do apologize I actually swore at the last consultant and said IL rather go in a telkom store...calling the call center is the pits..I wish I could screen shot my call log to back up my story..over 40 mins calling,6 different consultants..yet I'm still not helped.. My advice take this as constructive criticism and fix this problem!!!!
