Hp and incredible connection working together to **** customers

Took a hp i7 intel core iris xs on contract from incredible connection liberty mall pmb for personal use the laptop has got progressively slower. I have a similar laptop at work, and it's doing the samething. I asked the IT person at work what the issue with both the laptops and he said the processor are an issue, however my personal laptop is under warrantt so i took it back to the store, I was spun a story about the hard drive being an issue and that I need to install a ssd hard drive, anything to squeeze money out me, the tech said is a hardware fault and therefore its my problem, I should replace hard drive, this without testing, so i asked for laptop to be sent to hp, and the threat used was that if it's a hardware fault I will be liable for courier and other fees, nobody wants to take responsibility, nobody wants to help. Its seems incredible connection just lies about warranty and that hp is selling inferior quality products. My laptop is a white elephant that I am paying a large sum of money for. The lies have to stop and help is needed. This generation of laptops have an issue with the processors it needs to made known and especially if its trying to be covered up especially by the stores.
