Worst service EVER

I have been with Mweb for a couple of years now and we had our ups and downs with some technical difficulties like any other internet provider, I've been using their LTE 1st was with Telkom through MWEB but had some slow internet issues and they have upgraded me to a 2TB LTE anytime data, this was okay but still couldn't stream movies without buffering and so they have upgraded me to MTN and everytime they change your network you get additional charges such as Pro rata as well as a sim charge of R200. Yesterday I received a mail from MWEB to say that MTN clients will be throttled from 50gb of usage even though I'm paying for an uncapped LTE where I was told that throttling is only from 550gb. I called them right away to get behind it all after being waiting in the queue for almost 20min to speak with someone and had been transferred to their sales department. The lady advised me that it's best to change back to Telkom with additional charges once again for sim courier and pro rata all on my expense after I have already paid for a uncapped for the month and if not then I will be charged again the full amount next month for a throttled 50Gb and when I have asked her what MWEB is doing to compensate their clients that are paying for a full uncapped line but not receiving what we paid for she just simply said there's nothing she can do but for her to speak to her manager and find out of the manager will communicate to their clients what they will do to compensate everyone that will be effected and that it's MTN (the service provider) and not MWEB's doing but I'm paying MWEB for their service and I've expected MWEB to compensate their clients if needed to move to a different service provider because of this 50Gb throttling that was implemented right after the email was sent out 7 days after they have received full payment from their clients it rediculous. I must say this is the worst service I have ever received and is beyond furious that I have paid R689 for 50Gb throttled internet what a ****! When throttled your network speed drop to 1kb per second.. you cannot even stream YouTube videos nor Netflix without buffering. It's hard to reach thier customer service due to being placed in a queue costing you airtime by reaching unsatisfied results
