Investigate Trafalgar mismanagement of funds

I have been charged by Trafalgar 37% interest on my account. I have tried to ask why. The employee Nadine Bisset, took about 2months to come back to me. The only time she responds is on email only reacting, promising to fix what has gone wrong, late invoices with different amounts. Invoices are late. Communication is bad. I am being over charged. We need to investigate this agent as people are not happy with their accounts since they took over. Owners are not happy with the increase but they have "signatures of owners" that agreed to be charged higher than what is correct. Curtains are dirty, cracked windows are sealed with sellotape, carpets broken and dirty, lifts working of and off. The list is endless. Body corp must investigate our finances. I cant take this anymore. ******* at its best.
