Really bad service delivery

I was contacted by a sales consultant from Sa getaways in August 2014 and she managed to sell me a holiday voucher valid for a year .I provided the consultant with my banking details and the R300 for the voucher was deducted on the 25th of September 2014.I have not yet received my voucher and it's almost a year now, I have called their client service department several times and have even emailed them. I was promised by the consultant to receive the voucher by email within 2 days and I still don't have the voucher .I am very upset about the service I received and how many times I have had to escalate this issue yet I receive no assistance from Sa getaway, if this is how they treat they customers I think they should consider closing their doors.
