LTE issues

I'm not whats going on, I have been using Mweb for probably 2ish years now and have 4 LTE contracts with them. In the last 6 months working from home has been an opportunity for me. 1 of my LTE contracts is solely used for my work purposes and lately its been ****ty. It first started when loadshedding got implemented, I would only have connectivity issues in the last 30min of loadshedding but now? I cant even send an email without it telling me connected without internet. My area does not have Fibre so LTE is my only option. I only have 1 device connected to 1 LTE package at a time (which was never needed before). I have logged queries on my app/on the site but it automatically gets closed without me being contacted yet I am still responsible for paying my bill? Please sort yourselves out as I now cannot work from home anymore.
