Worse off after applying for loan

What a let down and harmful company built on fals adverti*****t it's to grieve about that the NCR do not investigate and follow up on cases on this website. I app**** for a loan on the 16th Sep by 18th Sep was preliminary and subject to T&C approved 19th Sep was spent on calls and emails trading hands and final approval with sms and confirmation in sms keep eye out for sms from your personal bank for funds. So spent rest of the day getting contractor's and avalibile funds I hade left in my account getting materials for house upgrade project. Ran into overdraft as sum people required deposits and others started with project to avoid rain. 20th Sep by 08:23 no money surprise,surprise I phone a very helpful lady that says sir very sorry you have to redo our phone verification but we sort it now maybe tonight maybe tomorrow morning or Monday morning. Pressure start building. Go through all the motions and before she says bye she ask for a favour my ID copy little dark can I send new copy. Witch i do with haste and imidiate 25min later another sms of approval of loan. No t&c no hassles full confirmation. But awaiting call I was promised as she would conformation of time loan will pay out 2 hours later nothing. Long short R600 later airtime and 5 calls they overturn my loan completely even blocking me from site and application no reason nothing. Try phoning customer care as I put in I'd no they drop call by saying baye. Need to visit lawyer's as I'm purple faced no money maxed on overdraft and contractors wanting to break down my door. *** must I do please advise me?
