deeply hurt customer

I am deeply hurt and unimpressed with the service received from the Ikhokha business. I bought a machine 3 weeks back and have been unable to complete setting up due to the lack of customer service from Ikhokha. I have been calling and emailing them but I am constantly met with an answer of “we will get back to you”. 24-48 hours doesn’t seem to end. When you think 48 hours is over, you receive a “we will give you feedback”. I have not received any actual help and this is negatively affecting me. It feels like I am stuck in a cycle of unnecessary stagnancy that will never end.
