Ignoring customer and incompetence

Our business acquired a business fibre contract with them after many emails, checking whether it is 1:1 "and strictly so" contention ratio on the product. i.e, there is no contention.

After installation and seeing that the line is not better than a normal "fibre to the home" line, we asked why, after which they noted that in certain situations there actually is contention. We then requested them that we want to cancel the 12month contract without penalty, since a product was sold to us that is different than agreed and discussed on email.

This has been going on since the start of August 2021, and they have been very poor in communication and getting back to us, various emails and phone calls, much unanswered. They first gave some irrelevant arguments as to why we did get what we signed up for, and then they just started ignoring us - even or specifically the Sales Manager.

We have now stopped the debit order on the contract, and followed up with another email stating so, and still no communication two days later!
