Further, despite all of the experience which seems to be claimed on Eze Legal Service's website, the company was only formed 9 days ago!

Timeshare Council is not, as the name might suggest, an independent body looking after the interests of timeshare owners. It's a trade body ("Activities of professional membership organisations" being its registered activity at Companies House). Its directors all seem to be involved with time share (or similar) activities elsewhere. For example, one director (Philip Watson) is also a director of Tobago Travel & Property Ltd, Worldwide Timeshare and Exchange Ltd, Worldwide Timeshare Hypermarket Ltd, Wealth Style Investments Ltd, Expectations Club Ltd and several other companies).
