Item not delivered, no refund received

I bought a titanium entertainment unit at makro on the 17th of November and they failed to deliver. I then requested that they cancel my order on the 22nd of November and even today, I am still waiting for the refund. It makes no sense that it would take them around 20 days or so to process my refund. I need my money, I tried contacting the store via email there was no response , I also tried calling but I have been unlucky their lines are always busy. I received a call on Monday from one of their employees telling me that the finance department promised to process the refund on the 6th and it should have been reflecting in my account on the 9th. It is also draining that I have to follow a whole well known store for this, this is unacceptable. Nobody cares to respond to your emails or to give you a feedback regarding your problems and the only way you get their attention is when you write here. I have been a loyal customer to Makro but with this kind of service, I am done with Makro. All I want is my money, it's been forever and I do have serious things to do rather than complaining about Makro. Someone please take this matter seriously, it might not be a lot of money but it still is my money. I will forced to let my lawyer write to the store because this treatment is unfair, I can't keep calling you guys as if you're paying for the cost, I'm drained now. You have already breached Consumer Rights Act 2015 and I doubt that my lawyer will take it lightly. You have 48 hours to resolve this matter, and bear in mind, I am not talking about a call where your assistant will promise me that the matter will be resolved. I am talking my money being processed, failure to do that, my lawyer will contact you. Thank you!
