Honestly do not know where to start, they crashed my Vodafone app so I couldn't check my allowances, then charged me ridiculous overage, took 4 months to get my app fixed and about 30 live chat sessions that 99% of the time ended up with them cutting me off. Promised refunds that have never arrived, callbacks I have never got, and to top it all off another £80 taken from my account today, despite being told yesterday it would be considerably lower 'this time' due to a refund they were taking off my bill (which surprise surprise they haven't) & (while I'm on the subject this refund was supposedly issues to my bank nearly 4 weeks ago? So how could it have been refunded and taken off the bill but neither actually happened?? Someone's telling more lies...). Constantly making false promises, I want to know if they are even regulated??? Honestly I cannot stress enough how horrific they are, worst company ever, everyone just go to o2 at least they treat there customers right!!!
