I HAVE HAD A CLOUD PHONE SYSTEM FOR MY BUSINESS CLOUD VOICE EXPRESS WHICH IS NOT FIT FOR PURPOSE!!!!!! IT HAS DROPPED SO MANY CALLS IT IS UNBELIEVABLE. I HAVE PLACE A ORDER TO UP GRADE TO BT ONE PHONE PROBABLY 6 WEEKS OR MORE AGO AND STILL HAS NOT BEEN SWAPPED. HAVE CALLED SO MANY TIMES AND JUST TOLD ITS BEING PROCESSED, THIS PHONE SYSTEM IS COSTING ME A FORTUNE IN LOST BUSINESS. ASKED TO SPEAK TO A MANAGER AND TOLD I CANT. BT IS SIMPLY THE WORST COMPANY TO DEAL WITH AND I DO NOT RECOMMEND TO ANYONE!!!!! BE WARNED!!!! THIS WILL BE GOING ALL OVER SOCIAL MEDIA NOW
