I switched from plusnet to AAISP when our cabinet was upgraded to fibre mostly because of the poor customer service fro plusnet. BT have ruined this company since taking it over who have a convoluted customer service process that passes you from one long queue to another only to find that yet another visit from Openreach needs to be book to find exactly the same reoccurring problem with no escallation to someone who can authorise a fix! My heart sank each time my router dropped the ADSL line as I knew I'd have to endure 2 hours with the phone to my ear listening to the entire repeater of music on hold, security checks and ineffectual, impotent customer service call handlers.

With AAISP, you get through to someone within a few rings who can call across the office to an engineer to help AND they take ownership of the problem calling you back with progress reports. That's the way is should be!
