Never been so disappointed

I went back to M Web as their service is extremely good , and I was getting very average service from the company I was with , they sadly could not give me LTE as I did not have coverage -so I took an DSL product 150G -free night time at 8m -after I started this , I started having very poor signal -sometimes 1m and 0.1 upload , I phoned them and asked them to upgrade me to 10m, still the intermediate internet continued , up to the point where I decided to cancel it -on the Friday night 01/09/2017 -I tried to cancel it -but again I could not even go on the internet -then on the morning of the 2de -was able to go on , and now cancelled it -but now it told me that it would only be cancelled 2 months from now -as I only could do it on the 02/09/2017 -not only that I then saw that they changed my product to an uncapped one that was more expensive than the product I agreed to -leading to me having to pay much more than I was suppose 2 -I lodged a query -and even phoned them the next week , up to now -no reply -no and pathetic service -SO disappointed
