poor service delivery

I moved to a new premises almost a year ago of which I then upgraded my package (100mb/s). The package I have been receiving is a speed of less then 50mb/s . My husband has reference after reference complaining about how we are getting a lower speed then what we are paying for and we have got absolutely no assistance for a year now. My husband then has requested a refund for all the months we have not received the service we were promised and still no satisfaction. This is a pure case of poor service delivery and THEFT. I am now highly disgusted that i must pay a fee to have a technician come out and come and test the speed on a your product, what ******* is this? I honestly am highly appalled by your service you give clients and how you can blatantly take money for a service you are not rendering and still charge me for a technical issue with your product. This is going against the Consumer Protection act as I am being treated unfairly.
