laptop contract with 10g data

Pathetic service to say the least...logged a call on 7 March i got a laptop contract with 10g data and only received 1g data...reference 1#***... no joy received i went back to the MTN store they logged a call ***...subsequently both tickets are closed but my pro rata data is not loaded... the store verified that every is correct on the system and a note is made that I should have received 7.58g data but nothing... Credit me or give the prorata data today.
