Worst Service to date

So 1st of April my wife requested a Settlement letter from D/A,Due to debit orders they couldn't assist with it at all and had to wait for it to be cleared, No one of all 5 consultants we spoke to assured they will contact us as soon as its available or contact us once the system is sorted.The following day we contacted them again at 07h45am the lady requested the letter and we waited....at 08h30 we called them again to follow up still no letter and apparently it goes through a system which can take 24/48hrs and a settlement letter is valid for 1day so how's that gonna help..Anyways still no letter 10:20am we called them again the lady said she can see we have requested the letter but they cannot do anything as its out of their hands to send a damn email and make sure it gets to us.15h55 still no damn settlement letter from D/A..no one even called back to follow up or just see if anything has happened or anything at all.These people just give the worst service ever after even speaking to team leaders and all they just couldn't care..I will make it my duty to let everyone know to never ever take a loan from D/A they just don't care about their clients at all. Worst ever
