Service not delivered & no response

I am an accommodation provider. I received an email from SA-Accommodation.co.za to list my business. New site special offering lifetime listing for R399. Had some initial questions to which they rep**** quickly. Then paid the money & listed same day (21 Dec). They promised to have listing done in 24 hours, with max 48 hours. Emailed following day to say I'd checked, but no listing. Emailed again on 29 Dec to say still no listing. To date (06 Jan) I have not heard peep from them again. I emailed them a short while ago, and hope to hear from them by Monday. This is NOT the way to get your website going and to provide customer support. I have worked in the Travel & Tourism industry for almost 30 years, and this is, in my opinion, very bad service on their part. If you are not able to live up to your promise, the very least you do is contact the client to update them and apologise.
