Incorrect billing. Charged my business account, for someone else phone number. Never got a refund. You ring them and you are on hold for 2/3 hours at a time. So, I have written to the Chairman three times. Jeroen Hoencamp. Each time I get a letter back asking me to ring them. Stupid pointless Company. Recently, cut my phones off for not paying the bill. Which they failed to collect via DD. Confirmed by the bank. After a 2.5 hour phone call, I realised that they have been billing me incorrectly. So. Unless I pay the bill. They will not realise my telephone numbers. But I am able to prove that the billing is incorrect. Utterly useless.
