Pathetic irritating service

I made a complain in September with insurances that I don't know in my account. I was given emails to send my query. I never received any response. I went to the store again on the 30 October 2021.I never received any response. I called to do follow up on the 05 September 2021 they promised to come back to me. Up until today Im waiting for the response. In the meantime I receive irritating calls from their collection department to pay.
