Business ProfileforTalkdesk

I was sold talkdesk in April of 2023. I was told I would be able to use talkdesk "click to call" feature on Apollo.io. After signing contract, I waited a month before I had to reach out to them to get my software working. Talkdesk then set up an "implementation call" with me and ** team. In this call, I was working with what had to be a new worker. Our call consisted of me coaching him through the software, and him troubleshooting on his end for half of it because he did not know how to use the software himself. By the end of the call, my software was still not working. They then want to charge me an implementation fee above what was stated in the contract for that call. Fast forward, and the ** worker ends up ghosting me because he could not resolve my issue. He sends me back to sales who tells me that they will have to access my Apollo account and do a load of back end work in order to get the feature working on my Apollo account. Which they again would need to charge me an implementation fee to do. I have since expressed my distaste in this and have tried to resolve the issue with the sales team for a refund, but they will not do so even though they withheld a load of information in our sales calls. My software is still not working and it has been over 3 months now, and yet I am still getting invoices to pay for the software + the implementation fee. It doesn't make any sense to me and I am not using the product. Nor does the product even work for the intended purpose i bought it without having to pay a bunch of extra money that i was never told would be needed in the initial sales calls. I am continuously not receiving replies from sales anymore when i try to explain my complaints. I would like the contract to be cancelled on false claims and withheld information (not to mention terrible customer service) and I would like to never be contact by them again.
