Disgusting service

The only way i can get any assistance from Wesbank is by laying a complaint. The worst part being through my complaining i save Wesbank from paying another of their over R30 000 which was not actually due to them but was meant to go toward settling my account. After all of that i still cannt get what i have bben asking for a month later. I asked to have the account settled and closed, they pay the settlement amount and send a settlement letter but the account is still active on my on-line banking. i have asked FNB to close it and they say only Wesbank can do that, than there's over R4000 deposited into that account which i ask FNB to trace as i assumed it may be a refund from my shortfall cover, FNB says only Wesbank can trace it, call Wesbank, theres no answer call the consultant who was assisting me, the line is bad and she just hangs up. a few days later the R4000 is removed from my account, with no one telling me anything about where it came from or me giving them permssion for it being removed. On top of all that , there are still charges being charged to this account, interest, premium and a lot of other things. Like, i do not understand why this is so difficult?
