21 day promise/policy is a waste of time

I logged a return for my laptop on the 17th of November. They picked it up the next day. The problem I'm having is that they have a 21 day promise/promise that states that if 21 days have passed from the date to logged your return and your item haven't been replaced or repaired then they would be in contact to see if you would rather recieve a credit/refund. It's now been pass a month since I logged the return. My laptop haven't been repaired and I was not credited. They now telling me that they gona send my laptop back to me. Its frustrating me. I phoned so many times but I get the same reply. No one seems interested in helping me. The communication is **** and pathetic. One of the assistants cut the call while I was explaining the issue to him. I dont think I'm gona but from them ever again. And I suggest others not to also buy from them. They make you beg. They treat customers like **** and have no idea what they doing. They make promises but dont deliver on them. This is one of the worst experiences I ever went through, had to wait for a month only for them to tell me that they returning back my item. Its bull****!!! The warehouse needs to ****en wake up!!!
