Hsense T5 Plus NO SIGNAL!

I purchased the T5 Plus in April this year. The signal drops so badly that i have NO coverage whatsoever (Its not my service provider as my whole family are on same network and its only MY phone) and when on charge it either doesn't charge or when i unplug it the battery icon on screen shows its charging!!!! i hadn't had the phone for two months. I've taken it back to Ackermans and have requested a refund! I have not heard from anyone from Ackermans. I've sent messages via Facebook and they keep apologising and saying its been escalated. I'm sitting without a phone and cannot afford to buy another one. I've been given the run around. I asked for a refund and mentioned all the complaints I've seen on this platform and the manager at Ackermans said I should print the complaints and take it to them. Why should I have to do this??I don't work for Ackermans. I am however a customer and the phone is still NEW! I want someone to contact me and id like a refund please!
