EXTREMELY BAD AND APPAULING CUSTOMER SERVICE!

After having paid R1000 for installation & connection and internet services ikeja only then informed me that they would be coming to install my device on the 23rd of April, now i fail to understand how this is possible to pay R500 for internet connection that i wont have - i can understand the installation fee of R500 which is justified. i then went out to call they're customer care line and after being on hold for more than 20 minutes i spoke to an agent by the name of Ntsikelelo who was extremely rude and unproffessional and shouted at me for seeking clarity regarding my issue. i then requested to speak to a manager and was passed over to a lady named 'Sam' who provided me with a number to send my banking details for my refund to be processed and AGAIN the number provided for whatsapp w-only gave me a system generated response. The service that ikeja has rendered has been extremely unproffesional and nor do they're agents have any phone etiquette whatsoever - they have no training at all on how to treat theyre customers let alone make theyre customers feel welcome. By the way this is not the first time i am a customer of ikeja i in the past experienced bad service but decided to give them another chance and it seems bad customer service is rooted in theyre business module. I WANT MY REFUND OF R1000 AS I AM NO LONGER GOING AHEAD WITH YOUR SERVICES!
