My company and I have had a business phone contract with Business Mobils for a few years now however I tried to contact them on the 29th May as we needed a replacement for a broken handset....It is now the 22nd June and I still cannot contact anyone even though their website states that they are operational. I have emailed, used the contact us, left voicemails and every other possible way and a month later not a single reponse from anyone
