Horrible customer service

I went to telkom to get the October deal, it was successful I received my SIM card only. When I got home I realized that the SIM card does not work on my old router as it was from another provider. I went back to the shop @ telkom kollonade to ask for help. 1. The lady by the name Nicky called the manager the manager took forever to attend me 2. The manager never even cake to see me. 3. Nicky tried assisting me but she did not have much information. 4. Manager still didn’t want to see me and talk to me. 5. I ended up leaving after waiting 2 hours for help in the store the lady said she will call me she took my numbers. I went back to the store to check how far is the progress as I was told they will call me back Thy told me they are still busy they will call me. Up to this far it’s been 2 weeks I haven’t received any call I’m struggling to use the SIM card without a router no manager called me no consultant called me my query went to waste yet I went to the store three times for assistance. The customer service is horrible management is ******** and they don’t care about clients clearly I was not a priority cause I already signed my contract they are not willing to assist me get the router yet it’s about increasing my monthly payment. All I wanted to do was to add a router with the SIM card only October deal cause it’s useless having the sim but soon they will be expecting my monthly premium.
