Bad customer service from Spirit Motorcycles in Cape Town

I have had the unfortunate displeasure of dealing with Jasmin from Spirit Group International trading as Spirit Motorcycles. They are based here in Cape Town and sell motorcycle accessories and clothing.. Im not telling anyone specifically not to buy from them, but I certainly am dissatisfied with their lack of service and its up to you to decide if you want to deal with a company like this, who does not offer the service of going out of their way for their customers. Here are the facts ...I purchased a motorcycle helmet from them on 22 Feb 2021 via their online site (im trying to shop online as much as possible for my and my families safety and the shops staff safety during covid times). I followed their sizing guide on their own website for their own helmets and bought the size according to their measurements that should have fitted me perfectly. The helmet arrived via courier, but it was far too small and could not even get it on my head. On 19 April I drove from the South of Cape Town all the way to their HQ to have it swapped for a larger size. (just to note here that the helmet has a protective film over the visor with a graphic on that will prevent a person from using the helmet without removing that sticker. I did not use it at all and had its protective pouch and boxing in perfect 100% brand new condition. I was helped by Jasmin, their retail manager, but they said that they dont have any larger sizes in stock. There was no other helmet their in their showroom/stock that i liked, so i asked for a refund. They refused the refund due to it been over their 10 day return policy. I explained to them that I phoned their company a few days after i received the product and spoke to a gentleman their who said that I could return the helmet as it did not fit (he did not specify that they had a 10 day returns policy). I told them that I have been suffering from covid related depression and have not been going out. Its not my fault that their sizing guide is incorrect and they they had run out of stock of my actual size, plus i already drove to them to return it in good faith but they refused flat out to give me a refund, even after explaining all of this to them very politely. I was actually quite dumbfounded and very disappointed by this utter lack of service to a very reasonable request, its their own product and in a 100% resalable condition. I drove back home feeling very annoyed with them. I then wrote a written complaint to their company email provided with the same information as above. they replied today to say that its ok now that they will give me a refund but i have to come all the way back to their shop to bring the helmet back again before they will give me a refund. However, i was there yesterday, with the helmet, in good faith that would give me a refund then and there. I gave them all the same info but they decided to pull 'company policy' on me that they couldnt give me a refund. All i am asking is that they send their driver or someone else to pick up the helmet and give me my refund, but they are refusing. I even phoned Jasmin today to check if they were seriously not going to send someone out and she very rudely would not let me speak or finish my sentence and kept talking over me while i was trying to talk to her, so i put down the phone in disgust.. This is no where near the level of customer service that I would expect from a 'seemingly reputable' company like Spirit Motorcycles and will never deal with them again. You would think that people doing business during Covid times would be grateful for any support/business that they can get and not take it foregranted and make sure that they give good service to attract more and loyal customers during this tough time for everyone.
