Poor Service

On 29 Jan 2016 I received a promotional offer from RCS via SMS that if I spend R3500.00 or more, I will be credited with R700.00 into my RCS account. Well, I spent just over R5000 on the 30th Jan 2016. Since then it has been an uphill battle with RCS to get the R700.00 from them. I have phoned them continuously as well as sent emails via there web site (which by the way is absolutely useless as they do not even answer these). Every time I phone them, I am told that a supervisor will contact me back. Good thing I didn't hold my breath, cause I would be stone dead by now. It is now May 03, 3 months since the promotional offer and I still have not from their side received a single correspondence. This is pathetic service and I think they are very quick to get you to use their credit but the very worst creditor to sort out any complaints. Is it because they are completely useless, or that the staff they employ are extremely ***********? I will continue to pursue this matter, and my next stop will be the ombudsman. Lets see if they respond to this in the meantime!!! Very dis-satisfied. Vaughn
