Hsbc are uncooperative inflexible & seem uninterested

this is is going on any social media I can get my hands on because everyone should know how bad and uncaring this company is.
couldn't make a transfer from my Hsbc account last Friday so phoned them Saturday. was assured the problem was sorted and I'd be able to make my transfer on Monday morning. Didn't work on Monday so phoned up. told it would be ok on Tuesday. didn't work. phoned Tuesday to make transfer over the phone. I was at work and didn't have access to my account so couldn't make transfer. was told I could phone up to 8pm next day to get it sorted. phoned just after 5 Wednesday. was told everyone went home at 5 in that department. phoned Thursday at 4.20. after 40 minutes the operator comes on the phone and says she can't hear me. I phone up again and of course it's after 5pm so no one can talk to me. I suggest someone bothers to phone me. that's not possible.
their online banking won't let me make a transfer and no one is available to talk to me after I finish work. they speak calmly and patiently but don't resolve any problems.
I can't believe how inflexible and uncooperative this company is. I will take time off work tomorrow and lose pay so that I can get all of my money out of this bank and never use it again. they should get zero stars.
