Poor client service

2 of my friends told me about the heater that was on special which they get from builders online. I decide to place an order and payment was made. 2 days later I receive a call from a lady telling that the heater I ordered does not exist,I ask how possible is that cause your website has it in different colors clue,she sounds like she's clueless so I request that your head office call to me to explain. Another 2 days passes and no one calls so I take it upon myself to find out what is the issue. I call your contact center and the first lady I speak to put me on hold and says she will check with the dispatch team, the call gets cut so I call again. The second lady explains to me that the heater has been discontinued and they will either refund or replace it with a similar model,she puts me on hold then the call cuts again, not sure if they do it on purpose. No one called back to come with a resolution to the issue,is that how your customer service works,so I will constantly make follow ups with you on a product that was advertised then processed successfully online but no one cared to communicate the back office issues? The level of service I'm receiving is pathetic from such a big company. I'm beyond disappointed.
