I purchased this in April, did not assemble until mid June so had been up maybe two weeks.  The thread(rope) that acts as the pulley is unraveling to the point that it is just being held up by a few threads.   I am afraid this will snap and fall on someone’s  soon.  Is there any thing that can be done here, love this umbrella and would love a new one to try again.  After two- three weeks used ( and only on weekends) this should not have occurred.   Thank you in advance.
