bad experience from Telkom and not for the 1st time

i received a bad experience from the 99% colleges that i spoke to. i had a query regarding the etu then i called telkom on the 17th February 2020, i spoke to a lady who i didn't write her name she kept me on hold for more than 30 minutes , with the query she informed me that on her side i dont owe any Etu. she informed that the matter will be escalated. She kept me on hold until i was hanged-up. im sure i called 5 times . Then i called again spoke to another lady in Durban who was a bit helpful as she informed me that she will call me back she never did . i dialed again spoke to Smangele Ngcobo who escelated the to the supervisor can rememeber her name she informed me that the ETU was taken by my internet and i need to thing as well , i got so upset as she spoke to me like that she hanged up without helping me with the matter. I called again spoke to Boipelo Masako in Jhb she informed me that Lizeka Ntabeni is busy and she with other clients and she if shes not done she will call me the next day , i was so angry as they were taking me to pillar and post. I was getting different stories from everyone . On the 18th i called again spoke to a lady her surname is Culu from cape town i asked if i can speak to one of the supervisors she didn't help me as well as she kept me on hold 5m then the line cuts off , i dialled again spoke to Bulelwa she was also rude to me and i had flu she informed me that im shouting at her i informed her that im in a car driving using bluetooth, i asked her to escelate me to another person that speaks sesotho. I asked for her surname she said shes not allowed to give out her surname. I then spoke to Matshidiso Hantsi what a person , you could hear that shes willing to help customers , shes very gud . i explained the issue that i had and asked if i can speak to a team leader but not Lizeka as she was in the same building with her she transferred me to Sifiso Maphumulo yoh training needs to be done . well he explained the issue but we didn't finish the conversation well as he said one word that i didn't like and still i told him that he has no right to say that to me , so i guess there was no better word to use he said yena otsebela kae , i told him that i cant be sitting on the phone for an hour and not get the helpof better explanation that i need. he informed me that thats the only explanation he can give he sounded boared . he sent me all the records but still i dont understand all that. Your consultants and team leaders need a better training
