worst service i have ever encountered

I wish i had more characters to explain all the stress-full nonsense i had to endure in detail but i will keep it limited and to the point. From the 31/10/2014 I have had Problems with my tablet. It has been in 3 times in for repairs and every time it comes back worse than before. This is the worst of them all. I was promised and convinced again it will be repaired properly this time around and told 'new parts' was used, only to find out disgustingly that the parts used to repair was of someone else's board that was used or possibly also broken too. I have proof of this because that previous persons photos is still on there. This is sickening to think i am promised new parts and i have to get **** like this. I have had it with fonechoice and there empty promises. I have spoken to so many consultants and explained so many times the errors on the tablet since October..I this morning contacted again and up until now the team leader has not returned my call after he promised that he would always help me especially in my case. I have never experienced such bad service in my life. All my life I had dealt with different institutions but fonechoice just the worst service delivery to date.
