Poor MWEB Service

I have had a problem with slow internet at home. On a lucky stroke I managed to get through to MWEB on Saturday 3 Feb 2024. Only to be told that I am paying for a high speed connection, but I have the wrong router, now I ask the question why did they supply me the wrong router in the first place. I was then told to contact the sales department. I finally gave up trying to get through to the sales department and thought I will send an email on the 9th Feb 2024. I have now come to the conclusion that MWEB is not contactable via email. this is really a poor reflection on MWEB and their customer service.
