TFG worst call centre ever.

I contacted TFG because i had a pargo package that passed its collection date and needed to be sent back to the warehouse so that i could be refunded. This happened last year October/November. I’ve called, and emailed all documents needed to resolve this. A few weeks later I called back because i still haven’t been refunded and was told that it wasn't actioned properly however it will he now. I asked the agent how i could trust that it will be taken care of knowing that I was **** to before and he said that I should just trust him. Its been weeks again and I’m still without refund. I was sent a survey which i rated very poorly, and thinking they would have a service recovery method in place that would actually take what i said and want to resolve my query in hopes of repairing the company name however doesn’t seem like they even care, because what is the point of doing a survey if it wont be analyzed and fixed? I am absolutely disgusted by this and have reached out but still nobody got back to me I am at the point if seeking compensation as i feel i have been to patient and understanding with TFG having worked for a call center i know things can be hectic however you cannot tell me a simple refund can take almost 6 months.
