Mweb poor internet quality and connection - Don’t sign up!!!

Dealing with Mweb has been an absolute nightmare. I installed a fiber line which has been so disappointing. I feel like I should have stuck to ETL because this fiber line connection is so inconsistent. Poor internet connection and quality. I have tried several times over a period of one year to have this sorted but it’s a nightmare trying to get hold of their technical support or even getting a call back. They have no courtesy whatsoever. Now that I want to cancel and move to another ISP they tell me I can’t cancel??!!! What??? This is ludicrous!!!! I have consumer rights and I’m taking legal action.!!!!
