Clicks won’t refund me on product that hasn’t arrived in over 2 months

The online team has been stressing me out. I’ve been trying to get a refund on an online purchase I made end of March. I first reached out to them mid May to say the item still hasn’t arrived and I no longer need it, I’d like a refund instead. They promised to get back to me but didn’t. I escalated to calls, I’ve probably called 4/5 times in the last two weeks. They’ve done everything from lie about the refund being done when it hasn’t, get me off the phone promising to call me back but they never do, tell me I can’t get a refund because my item has left the warehouse and will arrive soon and that also hasn’t happened or tell me they’re busy in meetings and can’t help me. My patience is wearing thin. Today their number is going straight to voicemail And I can’t reach them at all. I want my money back. This is so unacceptable, I’ve spent so much money on airtime as well, everytime I call I always get put on hold for forever. It’s unacceptable. I understand it’s lockdown and there’s a lot of uncer*****y, but they fail to communicate and now they’re wasting my time and money.
