Very poor and unacceptable service from Mweb

Should be zero stars No internet for over 2 weeks. No replies to online logging of calls. Phoned the callcentre several times. Held on for around 20 minutes each time. Promises made were not kept. Several times the call cut off, but I was not called back. Asked more than 4 times for the matter to be escalated to management and for management to call me. No one called me. How is this kind of service possible in a competitive industry. The worst service and lack of care, I’ve had in a very long time from anyone.
