Terrible customer service

I am highly frustrated with the service received by PartServe. I took a laptop in for repairs on 18 Jan 23, I was told it will take 2-3 days to send a quote/report. I am STILL waiting. I have called numerous times and often I cant even speak to someone because they are short staffed or offline etc. I spoke to Donovan a supervisor on 31 Jan, he advised me HP are low on stock but will look for another supplier and speak to his manager to escalate. 8 days later I call again and get told the same thing! This is extremely frustrating and terrible service received!
