phone not returned back after sending for repairs

Hello peter<br> Again fonechoice has taken my tablet for repairs since 11/01/16 and have not returned it, i have made numerous calls to them and since they do not give reference for the calls i have been communicating with a call center agent by the name of Fisher who has been promising me that my tablet was repaired and will be deliverd to me within ten working days which has never happend i fail to understand how fonechoice treat their customers so BAD and keep apologising only to do it over and over again all i need is my tablet repaired and back to me since im even done paying for it, for the past year i have only had my tablet for 5 months whereas money was being deducted every month for it this is so frustrating
