Pathetic customer service and hypocrisy!

I purchased a Telefunken Android tablet from Idealdirect in late August. When i received the product I had it kept until my daughter was done with her exams and then gave it to her last week. Over the past week i have noticed that the tablet has a few issues: 1. The volume control doesn’t work on certain songs 2. I have tried 4 different SD cards (2, 4, 8 & 32GB) and it does not pick up, also when I had the 32GB in we tried taking a photo and a message came up saying there is “Insufficient storage” 3. If you put in the SD card it does not allow you to set the “Primary storage” to SD card. 4. When you switch the tablet off, it does not come on unless you either hold it down together with the volume button for a minute or I have to reset the tablet. I called Rudolph at ideal yesterday and his words to me was that "He will have it uplifted and will have a replacement sent to me as well." All of yesterday went by and he did not respond. I get an email this morning stating "We would have to collect and sent it to our suppliers for an assessment and revert to you with repair/replacement option." Firstly that was not what he advised yesterday and secondly he was abit rude. This is certainly a factory fault as the tablet is still in its original packaging with the plastic cover it came with. I was then told that it will take between 7 working days to get it collected from myself and then sent to the supplier for an assessment which will take another week. Firstly i had to wait a good few days for it to be delivered. When it was delivered to me I called him and advised that i was unhappy with the storage space and i wanted to return it. He then advised that they would charge an upliftment fee as well as handling charges over and above the courier cost i had paid to get it sent through to myself. Ideal-direct are a bunch of *******s who provides terrible customer service to their clients and constantly changes their words. I also had major issues with them re-reimbursing the money I paid for a TV i had purchased which i was then told there was not stock off. It took almost a month in getting my money back. Rudolph also advised this morning that he will email the couriers to collect the tablet and up to now i have not received any feedback. I want the replacement tablet or my full refund. Extremely disgusted with this online store and it should actually close down.
