Disapointing to say the least

WiFi constantly buffering. Phoned them, they sent someone as they couldn't sort it out over the phone, charged a ridiculous callout fee that they didn't even mention would be charged. Then they had to replace our router by no fault of our own (ridiculously expensive), we made a payment arrangement and to no surprise they didn't stick to it and deducted the entire monthly fee plus callout fee plus router at once. And after the entire crazy expensive exercise our WiFi speed is still slow and lagging. Bad service and disapointing. I wouldn't refer
