Invoiced me incorrectly for £250, highlighted to them prior to payment reassured it was resolved. Payment taken out of my bank, I phone to complain to be told the refund request hadn't been made and had now been made but would be 5 working days. 5 working days later and I am told it will be 10-15 working days, requested call back from supervisor as they were on the phone. 5 hours later I call back having heard nothing asking to speak with supervisor again, stalling tactics used and then told payment would be 15-30 days!! Wtf?! Also supervisor was still on the phone apparently and unavailable, so told them I would be writing to the financial ombudsman and watchdog and how rubbish their customer service is. They were quick enough to take my money and leave me paying bank charges due to being overdrawn! Worst service ever!!!! Thieving gits!
