Bad service, poor poor poor

I called Edgars numerous times regarding my account, I explained to them that I've been unemployed for almost a year and that's the reason i couldn't pay my account. I explained to them that Im starting a new job shortly 01/03/2019. My new employer requested me to contact Edgars and make arrangements and get proof of email stating the agreement has been made for the debt to be paid. 24th February, I went to Edgars personally to do so.i spoke to numerous people who made the arrangements and confirmed that the will escalate the query to the relevant department for the letter or email to be sent. I than phone Edgars client service, accounts department and collections department on the 25th concerned I have not received the mail as yet. I'll speak to one person who says they can't issue letters, I than speak to supervisors who promise to arrange for the email, I've been on and off the phone with Edgars, calls lasting 30 to 40 mins per call and still they refuse to assist. Today 27th Feb I call Edgars again, explained the story over and over, the tell me they can't send me an email to confirm I've made arrangements I should just accept it's done. I explained to the lady again, I need this to start a new job, I've been requesting this E-mail for a few days now and I've been **** to and simply I've been told I won't get help from agents, supervisors and managers. I called my employer to explain the situation and I was told they'll have to put my application on hold until I get such confirmation. I asked the manager if she can just send me an email stating I have spoken to accounts department and I've made arrangements, that's it, she said no. Now either I wont get the job or I'll have to wait another month. Edgars is very inconsiderate, me as a client contacting them to assist me which will obviously in future be beneficial for them meaning I'll be able to pay my account. Edgars is one of the worst call centers and staff I've had to deal with ever. They gave me reference number which means absolutely nothing cause on the recorded line one thing is said but the notes on the system doesn't correspond to what I say I've been communicating to every new person I get in contact with. Inconsistent.
