Atrocious customer service! After numerous of occasions having faults resulting in Vodafone changing our router time after time, the broadband service has now been down for 9 days with no sign of it being resolved.
I am working from home and have had to buy an additional data package from my mobile provider in order for to hotspot. Openreach came out and confirmed the line was a great line and our broadband was running at 13mb!! that was 3 days ago and still nothing from Vodafone. My husband has spent a ridiculous amount of time on the phone being cut off (nobody rings you back if this happens, you have to attempt to call again and being the whole process with someone else), speaking to people who aren't listening, repeating himself, and as i type he is now on live chat escalating the complaint where yet again he is repeating everything! he has requested our contract be terminated and we have to give 30 days notice and pay for the last month. the main complaint we have is why should we be paying for a service we aren't getting, let alone having to spend extra money buying additional data in order for me to work. they have said if we simply cancel our DD due to our dispute then we will then incur a failed payment charge. Now, surely the best way to deal with this is to terminate our contract with immediate affect at no fee and not look to resolve the problems by sending out another router at costs to the company. really we should be claiming compensation for the additional costs to us and the inconvenience as well. We have now gone with Virgin who are providing 500mb to the measly 13mb we were getting. Given the current situation around Covid 19 and more people having to rely on their connection in order to make a living after being told to work at home, that companies like this would be working with their customers not against them.
