Mweb wifi

Every month just before the end of the month we have problems with our Mweb wifi. It either shuts off completely, is slow or says our bundle is depleted. Our bundle has never once been depleted, we monitor our data usage everyday. I have tried phoning and using the live chat on the Mweb app, both are absolutely useless. I phone in and I'm on the line for half an hour and it says my call is first in line. This is ridiculous and unacceptable. I have work to do from home, now I have to spend extra money on data to complete that work. I would 100% not recommend Mweb to anyone.
