Worst service and repair work

\i have been using Teljoy for 5 years, I have got alot of items through them and mad show i was always up to date, had a lot of respect for them as well till now..... I sent in my Hisense C20 for battery fault/slow system(freezing etc) , they phoned me the next day to tell me that the battery was indeed faulty and that they will place an order with Hisense, I dont mind the fact i waited a month for my device to be returned, the problem that i ahve is that the phone looks worse than what it did when it went in, i honestly think they uses it to skate down the passage... the technician glued it back together after replacing the "new" battery, when i sent it in i sent it with the original charger, however i received it back with a Lenovo charger, best part i waited a month to receive a phone that is giving the same issue that i sent it in for... I phone Teljoy and no one helps, they say they will escalate it but nothing happens... Thank you Teljoy for making me feel like a number and thank you for making me see the real you.

I paid for a month for a device i wasnt able to use, when i get it back its still not working, must i pay for another month and wait for it to not be done properly again? You guys lost that awesome service delivery and it is sad.
