VERY BAD SERVICE

Been stuggling from September to sort out bankint details that should have been changed on my MFG contract, been following up weekly but no response on my emails. They said that the supervisor/manager will phone me well I'm still waiting. I have been dealing with 4 different people and no luck. Yusrah Rass did not even let her supervisor or manager phone me back. I have send how many emails and I'm not getting any response.
