Lack of assistance

I purchased a ryobi angle grinder in November and it just started getting hot yesterday I stopped working with it until this morning when I turned it on and it just stopped working I've spoken to the store and was advised that the Manufacturer is working with skeleton staff and that I might only get a response next year. I'm so angry because I was in the middle of a job which I'm now unable to complete and then this is the type of service one receives. So how does one complete a job which you have a deadline for only in next year due to faulty appliances? The store isn't of much help I understand it has to be taken away for assessment but in the end the result will most likely be an exchange for a new one and then i have wasted all this time for a simple solution that could have been done in the first place I'm so upset with this piece of junk I bought!!! Also I need to spend money to get to the store and return empty handed and then go back again please make it make sense as to how the staff are also nonchalant in the store with very bad habits of looking at customers when we want to pay then they point at each other who's gonna assist the customer but everyone is available. Very bad!!!
