I have been frustrated for a while now that several active service providers I would love to see never display their phone number. I understand that this may be because there are some twats and time wasters out there who mess them around, but this has to be only a minority. They must be losing so many genuine punters that surely displaying their number would be worth the occasional hassle.
And before anyone tells me to use the online booking or email, I have done so, got my computer hacked and a virus, which was a lot more damaging than a hoax phone booking. Most phone bookings I have made require at least 2 phonecalls or texts to confirm, and the people I have seen confirm that the genuine bookings far outweigh the hoaxes.
So, come on, all the others. Get your number displayed. I could be your next client!
