Frustrated with poor service and no communication

I orderreed a pool cover end of June 2017 as per their promotion then. Instalation was indicated as 14 days after payment which should have been July. I made payment in full wrong instalation of a different cover was done in october after I had to phone and send e-mails. Cover wss collected 6 November to be replaced by correct cover. Till now 5 December 22:07 still no cover or any communication from them. Correct cover was due 10 November.
