No communication and they disrespect their customers

I app**** for funds which I needed quite urgent, then I was provisionally offered the funds. I sent all the documents requested to AB docs and copied in the supervisor of the lady assisting me. 3 days later no feedback received. I called for an update the lady just told me someone will call I must wait the final offer is on their system. why is it taking almost a week to finalize the offer ? I emailed the supervisor but they also just ignore the emails. so much for fast and efficient service.
