Poor customer Service

I am utterly disgusted with the poor customer service from Cell C .I called the customer care yesterday(19/01/2023) and was almost 15minutes with an agent repeating change of details over 5 times,been through the whole process and she kept saying her system being refreshed so eventually she did the change and i didnt even take her name ,i do know that calls are recorded.I called in today to get the statement to be emailed to me and the details hasnt been changed so icalled customere care and after doing the security check the lady says i failed and yet all correct details was given so how i failed only God knows.I am a subscriber for 22 years and i am shocked to say the service levels has dropped drastically. I dont understand just to change details can be such a difficult task for an agent to process.Since yourl have recordings listen to calls and please train your agents.
