Bad service from Wisan

I dealt with Wisane on 30 May 2023 trying to establish the amount I will be debited which included a promotional discount for 2 months. She passed the request to her supervisor who was supposed to get back to me. She advised that the if I didn't hear from the supervisor, I should get back to her and she would follow up. She also asked if I could rate her service. I received an email from her asking to rate her service on Hello Peter?(I assumed it would be for her company) However, since then I heard nothing. I sent her a follow up email on 2 June 2023 asking about the progress and had no response. I sent another email to her today saying that I was not impressed with the service. I immediately received a call from her saying she does not know what feedback I was waiting for since the amounts were worked out. However, noone communicated these amounts to me. She was sarcastic and unprofessional. I told her as per my email and ur discussions that I needed feedback regarding what amounts they were going to debit, however, I refused to speak to her further and dealt with another agent Nazley instead who seemed more professional. Let's hope she follows through with the request.
