Error code not cleared

I was given a DSTV walka as a gift, tried to have it linked so that I could use it. It gave me an E100-4 error code. Contacted the call centre 3 times, was then given an alt number *** (remained engaged) then requested assistance via DSTV facebook page, at 14:52 then by 20:35 I was informed that the facebook team could not assist me. Then at 07:50 on 20/07/15 I was informed that my DSTV mobile service had been reset and it would work, after numerous device resets and rescans the service error is still showing and I am still unable to use the service at 12:38 on 20/07/15
