Bad customer service and TLs who do call avoidance

I had on issues on my number when I called Mtn the first consultant had network issues okey fine no problem.... I called again the second agent was very rude to me when I said may I please give you the number I need help on the agant said why didn't you call us with the number you needed help with 😐😐like how do I call using that number when it's not working guys........ And I said it's not working she said is the puk blocked😭😭😭😭like what is that....... She went on to say the question she asked needed an answer! But what made me upset worse is when I was transfered to Team leaders almost 3 times and they all avoided me..... Why does Mtn pay team leaders when they don't take our concerns seriously? How can I call 9 times in a day and not get assistance..... I have contracts with Mtn I want to cancel becouse those people don't care all they do is to take their salaries and go home...... Today I said I want operations manager to call me guess what the TL didn't even try to reach out to me I'm still waiting even now..... Like I'm so ****ed off knowing how difficult it is to find work on this earth but u have MTN staff who don't care about us as customers it's a disgrace regards Nokwazi ***......
