LENOVO IS THE WORST COMPANY TO PURCHASE A LAPTOP FROM!!!!

I have ordered four lenovo laptops, in the same month. Two of which are not working optimally, I have contacted Takealot and sent both laptops in for repairs - one laptop, nothing was done, after two weeks, the laptop was returned with the same issue. The second laptop, was with providers for over a month, and was returned in a worse condition that what it was sent in. I have logged returns again both requesting a refund - I am told that the issue cannot be dealt with takealot, but rather with the supplier, and that a refund cannot be promised. This is appaling, this entire process is holding up my business and my staff cannot work this way, the delays are ridiculous and there is no sight of resolution. Lenovo has attempted repairs on both laptops, twice now, and each time the devices are returning in a worse condition than when sent it. Lenovo is refusing to refund me for these laptops. we are back in May, both laptops have been taken to partserve and returned again, the laptops are scratched and damaged, the hinge on one has been fixed, however, there is now a software issue that doesnt allow me to use the laptop. I really do not know what more to do. This is pathetic, i have bought these laptops only for them to be in repairs back and forth since February!!!!!! HOW IS THIS OKAY???????? I am actively looking for other ways and means to complain because I am not getting any joy. At this point, do i just throw these laptops into the bin and incur costs to purchase new laptops? what do i do?????
