failure to service me

i do not understand why is my tablet still with you guys when i took it for repairs, this is a new tablet that freezes and does things i do not understand, i owe you guys five thousand and something simply because your service and tablets are poor, now you took me to Shapiro Shaik and when they miss a debit i must see how it can be replaced i mean i have paid home-choice and they have never had a problem with me and my payments but you guys are literally something else, rather cancel the contract and keep your tablet that works for only two to three months. i mean even Pep store R1500 tablet works perfectly, i decided to take the table from Fonechoice thinking it was a quality producing company like Homechoice but today i regret the decision i took...utterly disgusted by all that.
