MULTIPLE ISSUES ON REPAIR

I have sent my acer tablet in for repairs about a month ago for a loose charging socket. The tablet was in working condition as I did a backup at incredible connection the same day as it was booked in. After 3 weeks of no communication from incredible connection I phoned for a progress report on my unit. The tech support lady laughed when I couldn't immediately find the job number on my job card and corrected me. Upon giving her the job number she told me that my unit has already been received by someone else. I went to the store and the store manager told me that it seems it's been given to another person by mistake and they will review the cctv footage on the weekend and get back to me. I was contacted the Monday where I was told that they where mistaken and the tablet was stil at acer for repairs. And it had water damage and battery wasn't charging a swell as a broken bottom plate. Not what I sent it in for anyway I asked phoned acer at incredible connection to cancel the repairs and was told there is a quote cancel fee that is to be paid that's not communicated in the t&c but incredible will pay it and I can have my unit in one working day it has been a week now.
