Bad service of the job

I sent my IPhone for screen repair after dat wen my phone comes back de other part of de screen is not working. Wen I emailed dem dey promised so sort it put but nothing is done dat is since last year till de date. Dis is not a company to do business with dem I even regret taking de phone Tk them if I may find other company who can fix dis mess I would appreciate. Dis Smartlab is really bad ppl to do business with them if ppl can hear me dis is a no no company to do business Tk do business
