Pathetic customer service!

This is such a disgusting business to deal with, i bought a TV online on the 28 November 2019 and i have not received it. I cancelled the order 2 weeks ago and requested a refund and they are now duck and diving, whereas i am the one that is contacting them and they are quiet. this is frustrating because they want us to pay in advance and when they have to pay the money back it is difficult for them to do so and their consultants are not easy to work with because they are the ones that gets upset before i as a client is even upset. they are so unprofessional because they are supposed to be updating the clients of any delay and not wait for me to call them in order for them to update me on the status. Even when you go to their branches they do nothing they just tell you they have to call what nonsense is that? i want my money back i have been patient for too long.
