MWEB POOR customer service

I am a customer of Mweb and I am unhappy with their customer service. I called MWEB on Tuesday to down grade my WiFi package. The lady I was speaking to said their Retention department will call me back to finalise the down grade. I am still waiting for that call even today. This company has a tendency of not calling back customers when a customer has been on the phone with a consultant trying to get help and the phone cuts. They never call back, as a customer you must recharge, if your airtime got depleted, and follow all those many options and prompts, wait on the line to speak to someone new and tell the problem you have from the beginning. They take customers for fools and are very inconsiderate of their customers. I am working on canceling my subscription with this company. It is not customercentric at all.
