Worst service

I laid a complaint on the 10th Dec, they gave a ref no. And promised to call me as soon as possible. Today it's the 13th, consultant tells me that I should wait 48hrs for my complaint to be resolved. I'm very frustrated as I have 88gig of data on a Sim card I can't use. To top it off call centre agent Lehlohonolo dropped the phone in my ear.
