Started out so well but went downhill

Fibre product mostly works well but whenever you have a problem it takes an age to get resolved. I've had to contact support three times in as many months, and it was like pulling teeth every time. I've now been without fibre for three days, leaving me scrambling for alternative options. I have a case number but have not heard anything from them since. The cancellation e-mail is sitting in my drafts ready to be sent as soon as I contact a new provider.
