Too good for new customers

Trying to order Uncapped Fixed LTE via all the available options, online, via WhatsApp and phoned in 4 times in order to speak to a sales agent or just get my order sorted as a new customer and have been put on hold for long periods of time only for the line to be cut of...waist of my time and money. If this is how your sign up service performs how on earth do you make money?
