Bad customer experience

They have bad customer service, in terms of communication and being truthful about their policies they don't follow. A ”15-20 days” delivery time has turned into 3 months, there's nothing in place to make a smooth refund, you must hound them on all their social media platforms which is unprofessional they can decide to ignore you or answer after 5 business days. It is one shop I won't recommend to anyone. If there's a way to recoup my money I would appreciate any help
