They Do Not Care about the client

I am a dissatisfied customer because i took my 10" Tablet for repairs at the store on the 29th of October and was told it would take roughly 7 days but not more than 10. It is now 19 days later my item is still not repaired and the manager together with the technicians dnt have the decency to even call me to tell me there are delays. I had to go to the store myself. Only to find out they closed for renovations and there is no one i can contact about my device. Head office transfered me to a repair centre in Maitland who could not find my device on their system. Finally they reopened and i managed to get hold of them and they say they still dnt have the parts for my device. And that i should expect to wait another 2 weeks for the parts to arrive. Then only they will fix my device. I booked in my device on the 29th of October it is now the 17th of November. And 2 weeks from now we will be in December. The worst part is that Basil the Manager and his technicians do not have the decency to call me as a client to update me. I have to waist petrol and airtime to find out whats going on with my device. The worst service ive ever got from any store.
