MWeb's incredibly poor performance for this long-standing customer.

I have been an MWeb customer for many many years. I have gone through their various iterations from Icon to the current MWeb. On many occasions my MWeb account has let me down in a number of ways. 1. When I was travelling overseas it was an absolute pain having to change smtp addresses our use another service provider, just to send out emails. 2. Over the years MWeb have obviously had various issues and have chosen to, unannounced, change various settings. This left me having to contact MWeb to try and sort out new settings. 3. MWeb's very poor conduct of their server has meant that various other service providers have blacklisted MWeb clients. This had a very bad effect on a number of my MWeb Clients where my email addressed was blocked and I was unable to send emails to these Clients! Guess what? MWeb did not even have the common courtesy to advise me what this was about! 4. Recently MWeb decided to make another bunch of unannounced changes that meant that I could neither receive or send emails form my Telkom LTE modem. My computer technician took my computer away to his place and lo and behold. without changing any settings, all my backlog of emails came in and he was able to send emails out. Please note carefully that not one setting was changed! 5. I called MWeb yesterday evening and their attitude was that because my email worked through Google that it was not MWEb's fault! The lady from MWeb even told me that my computer technician did not know what he was doing! 6. MWeb has a duty of care to ensure that any changes they make are fully thought through and that every eventuality is catered for. Sadly my view is that MWeb have an attitude of "don't care a damn". 7. MWeb has not yet had the courtesy to reply my email to them demand that they resolve the problem.
