Very unprofessional customer support from debt review department (Lewis)

I received a Sms from Lewis stating that I should contact them for dent review refund. I called on 9th April, agent asked me to send id and bank statement via email. I sent it the same day and she confirmed that she received it. It would take 48 hours for her to provide feedback or money to be refunded. No communication whatsoever, she did not call back, she does not respond to my emails. When I call them, she is on lunch 1 hour before her shift ends. I called several times have been transferred from one agent to another. No one seems to be able to help, not tell me who can assist. They are also not able to tell me how much the refund is for. Very very bad customer service 😡
