Annoyed is been gentle, This company has caused me to have a mental breakdown..I was transferred without choice as my company had gone bankrupt.....from that month the stress began..sending me a bill for £800 ,i was Annoyed but paid £530 of it that day as thats the only money i had ....they then sent me another bill £900 . I told them i had payed £530 already (they said i hadn't and that they had refunded it back to me ) bank statements ect later to prove i had payed them ....I argued and said just put me on a pre payment meter as i carnt do with the stress. Meter put in and they said it needed a change as it was faulty , then they have the cheek to put another debt on it of £550 , I had to argued again and take it to the odbusmen this time they said they owed me £350 ..'really' ..then from then it still went on to more stress !!!! ..i couldn't top up the smart metre ...4 months of ringing every Monday for them to say "we have loged your complaint and WILL get someone to call you back " NO ONE EVER CALLS BACK ....Week later i call again ,"We can see you have a complaint issued so we carnt talk to you THEY will call you back" REALLY (that just never happens )......4 months and no one has called back ... and a total of 39 hours of Recorded calls to -date and the issue still hasn't been resolved (they have also held me hostage since December now so i carnt leave the company either due to the machine not givinga reading ) .......Please i beg you DO NOT CHANGE TO THEM as there customer service is horendus ..x
