No service & unavailble to contact

I was contacted by RTR Distributors for a 10 day holiday voucher X2 at the amount of R600,00 In December 2013<br> The amount was debited from my Cheque Account in December 2013, I received my letter confirming the payment in February 2014 only, since then I was unable to be able to book the 10 day holiday, the number for Getaway has changed and the Call Mail box as well as the E mail is full and I am unable to book any holiday.<br> On numerous occasions was I contacted by RTR Distributors to try and sell me more vouchers on explaining that I was unable to even use the first vouchers the response is Ma'am we will get back to you regarding the issue up to now no success.<br> I would like to get my money back as this seems to be a useless case I don't think I will ever get my 10 day break away as the vouchers is about to expire.
