Lazy, terrible service and not willing to help!!!!

Want to complain about Takealot.com as well as Omnitec. I purchased a 4TB hard drive last year that stayed safely its it hard drive case that i purchased with it, and with less than a year of occasional usage it started to crash. Would stop working, very slow when using and transferring data on or off. I eventually managed to get some data off of the HD and then i logged a return with takealot.com. After the device had been returned to the supplier i got a message from Takealot.com saying that the supplier said there is nothing wrong with the device and that the issue is my PC and they will be returning the device to me. I told them there is nothing wrong with 2 of my PC's that i use on a daily basis. I have a total of 8 hard drives and don't have any issue with them. Told them that the supplier must contact me. After speaking to the supplier, they told me they didnt do a deep stress test as they should of as i usually transfer large amount of data at a time they said they will do that and let me know. Weeks go by and no answer. Takealot.com keep messaging me saying that they are waiting on feedback from the supplier. The supplier clearly didn't want to give feedback as it doesn't take weeks to give feedback. I demand their contact details but with no luck. I just received an email from Askieka.P telling me that the supplier has agreed that the hard drive is faulty but they wont refund me as the unit is physically damaged. Which is highly impossible as it was always in its protective case even when using it. I see they attached photos, which shows that the small cable it comes with is damaged. So they saying that is the reason why they wont refund me. Firstly the cable wasn't damaged when i sent it, If it was they would have mentioned that the first time around and secondly you can see the cable has been cut with a pair of scissors or a blade. They are trying to find an excuse to not pay out as it is still under warranty. A few other names of the people that mailed me about the hard drive telling me they waiting for a response but didn't bother and refused to follow up with the supplier but would rather sit back and do nothing and wait for them to get back to them.
