Rude Call Centre agents & False Advertising/marketing

I would like to lodge a complaint against telkom and it's rude agents that are supposed to be resolving our queries when we call but instead go on to behave like they are doing customers a favor. I. Have tolerated this numerous times and have noticed each time you would like to escalate the matter further by speaking to a team leader or supervisor on duty. It's always unfortunately there is no team leader available I will lodge a call back. No one bothers taking ownership or even making it worth even calling the telkom Centre when having queries. You will receive an email saying case has been lodged and then resolved with no feedback from a team leader as promised clearly using this network provider is self sabotage Yesterday on the 19/05/2021 I received an offer/advertising via sms that stated the following "Telkom amazing offer, two months left...recharge with R15 before 17/06/2021 and get 500MB of Allnet data on us. Free data is valid for 30 days. Ts & Cs apply." This was not the first time I received an offer that was clearly misleading and false advertising and marketing. I then recharged twice with 12rand as the banking app has limited options I received nothing. Today 20/05/2021 I recharged with 10rand and 5rand to make it the 15rand as it's not easy to get a straight 15rand airtime at the shops. I really don't know if telkom is aware of this or they rather have their majority customers port to different networks. At 17.57pm I then called telkom to speak to a very rude agent who said her name was Nosindi/Nosindiswa couldn't get the name quite correctly and then I explained the query she clearly made a complete fool of me asking me to read out the sms and then went on to say she has no knowledge of that sms clearly I am the only one who knows about it or better yet received it. I asked her what needs to be done as this is misleading customers and false marketing where do I lodge a complaint she said arrogantly with no sympathy she will lodge a case. When I asked to speak to her team leader she told me how this was not her fault became more rude. I told her it's not the first time I ask for a team leader and then never get any or for a call back and explained her frustrations. She told doesn't want to fight with me. As upset as I was I asked for her name again she transferred me to the next agent by the name of Bongiwe who hung up on me. Is this the type of service Telkom is promoting to its customers? Why are you even false marketing and advertising in the first place?
