Bad customer service

Tell me about the worse service. I requested a quotation for tyres and I got one ,few days later I purchased tyres and the communication was good throughout until I made the payment. Payment was done on the 1st of May 2025 then a POP was required and I forwarded it. To my surprise I was told that the tyres were under quoted and I need to top up. The funny thing and most disturbing is that I called first and they I requested to be sent the quotation via email, which I got . I need my tyres and no one is communicating as to what is going to happen. I had issues with this company 2 years back and here I am today again with a similar issue, no man this is just the worst customer service.
