Poor Customer Service

I sent an email to their customer support regarding the slow internet speed I was experiencing for over a couple of weeks now and how it was negatively impacting my work. This was shortly after upgrading my package to unlimited since I was very pleased with their network. I was then informed I would receive feedback within 24-48 hours for them to investigate , instead I got a generic response about them advertising their 5g SIM card . Clearly customer service is not a priority. There’s no prompt feedback or sense of urgency when you need help from them . This is very disappointing considering I left Cell C for this kind of service
