Home connect Is refusing to cancel a contract I no longer need !!

I’ve been trying to cancel my Home connect contract for the whole month and none of the consultants can assist because they are not allowed to cancel contracts . I apparently have to do it on the app , I’m unable to as their app isn’t working or it’s just loading . I repeatedly logged queries as well and to this day I have not been assisted . this is so crazy because I have been with them for 4 years and I’m moving and don’t need the services anymore but this is the service I get!!! They made sure their cancellation process is hideous so we are just compelled to be stuck in contracts we do not need . This is absolutely ****ming behaviour!!
