Official Complaint for urgent escalation

I am writing to express my deep disgust with the service I have received from your sales team particularly an agent by the name of Zintle (That's what she said her name was) on the Friday the 28/03/2025 I inquired about signing up for the rain wifi and router this agent called me and got my details for sign up and delivery I was very patient while being held up for over 10 minutes on the phone trying to ensure that she has all the details needed for this sign up once she had all the details and said an email came through with a payment link I thought that was sufficient enough I let her know that i'd received it and i'd sort that out once i'm back home but i'd need to go for now and I was already on my way out and stilllll patiently sat for 10+ min while she went on and on she completely disregarded what I was saying and said she'd call me back in 5 min to give me time to connect my account via the link when I explained again that I would sort it out when i'm back this woman cut the call mid sentence I responded to her email asking if she cut the call and only then did she try to call back a few minutes later I found that extremely rude I do not even know why I had to be pushed in that manner when the email clearly states that the payment link is valid for 48hours and as a result I decided that i will not be signing up through someone who has no manners if I were to even move forward with the service I do not want any dealings with this agent and I will not be signing up through them at all, it got worse today when she proceeded to call me and say she was calling to find out if she should "cancel my sign up or what because i can't honestly be running away from R1" ????? I got very upset and she cut the call on me AGAIN this is EXTREMELY EXTREMELY RUDE and unprofessional I will not be disrespected in the manner how is it allowed for agents to try and belittle ,bully and cut calls on customers??

If this is the service I am receiving during the sign up stage I cannot even imagine what I will be met with once i've signed up and possibly encounter problems I'd need assistance with I am not impressed at all I would like this matter escalated immediately
