Extremely Poor Service and Incorrect data allocation

I am so f***** ****ed off with this TELKOM b****** network, i have been waiting for them to attend to my query that i logged more than 2 weeks ago, they have been allocating only 50% of the data that i pay for on a monthly basis and i was told they will attend to my query in 72 hours and 72 hours later no feedback and i have been calling them every other day and i hold for over an hour before i can speak to someone and when i do i keep getting a response "your call has been escalated and is been attended to" for heavens sake i have kids that must do online classes and i have had to buy data and yet i have paid them in time all the time i am so frustrated because i cant even speak to the supervisor or manager and i keep on been cut off and just now i was "transferred" to speak to a team leader and they were having a chat in the background and after holding for more no one attended to my call and i was dropped yet again taking me back to square one where i have to hold for another hour...I have another contract with vodacom and i have never experienced this during this lockdown I am so frustrated i can scream. I cant wait to cancel my contract with them end of May. Telkom is the worst network with the most outrageous service. I will NEVER EVER recommend this network to anyone even if their money depended on it. Who can i talk to to assist me with my correct data allocation because i am worried that i will not receive my correct data again this month and i will have to keep buying data for kids to do online classes.
