Pathetic service & verbally abused by an agent

I would like to express my frustration in the calls I receive daily from home choice agents. Without fail I get 6+ calls daily looking for the account holder,who is my mom. Each day I have to explain that they need to contact her on her cell number as per their details on her profile. I'm fuming about the call I received on the 22/01/22 @13h15 from ***. The agent was beyond rude...I explained to her that she needs to contact thee account holder on her cell number as per their details,I then asked what was the call regarding so I could pass on the message. The agent took on with me,she went on & on telling me that it's rude to ask that question,yet the nerve of them calling daily without fail & I constantly have to request them to remove my number from my mom's profile... She was a Xhosa speaking lady who spoke to me as if she was talking to a rude teenager. This is beyond rude and unprofessional. They already have herd but when they can't reach her they phone me a dozen times. What time of marketing is that? If a client isn't available how can you call more than 6 times daily. Also why can't they update on their system they tried calling client or some sort of history notes. I will take this to helloPeter for showing the world what type of staff you have. I've never felt so abused verbally on my own personal phone.
