SMD Technolgies very unreliable

I initially sent in my tablet in for repairs to have the charging system and the back cover replaced. RAM couriers picked it up on 4 April and returned on 13 April. The charging system seemed to have been repaired but when charging it stopped at 63%, I used it until it needed to be charged again but it did not charge and the back cover wasn't replaced it was still damaged. The tablet was collected again by RAM couriers on 25 April, I was set to receive my repaired tablet on Monday 8 May, as per the telephone conversation with the RAM courier ***). However, after countless phone calls on the day, the courier never arrived. I then phoned the RAM office ***) only for them to tell me that they can't find my parcel on the system and they don't know where it is. I phoned SMD on 12 May and the consultant was meant to call me back because they too didn't know who had my parcel. I was sent from pillar to post and people promising to call me back but they never did. On 15 May I was sent an email of a screenshot of how and when the parcel was dispatched and a promise that delivery would be arranged. Since receiving the email no further communication on the actual whereabouts of my package and when I will receive it were shared and I followed up on this on 18 May. On 19 May an email response was sent which copied in Caronice Brenes, Fabian De figueiredo, Mlungisi Mkhize and Teboho Tsosane requesting that they arrange fro the urgent delivery of my package. To date it's a month later since my package was collected and there has been no communication from SMD, in fact I suspect the package has been misplaced and now they are just doing a back and forth to cover their tracks in the hopes that I will give up and forget about my package.
