Surecheck does not work

Surecheck does not work and I do not get any RVNs or TVNs via my cellphone. I called the help centre and they were useless, telling me to switch my phone on and off and to log off and log on to the website again. This does not work. What kind of advice is that anyway? They then mentioned something about interference from wifi connections? What has this got to do with with sending messages via the cellphone (3G) network? I sent an email to the contact no. on the website and am yet to receive a response, this after a few days. I tried making a transaction a few days later but to no avail. This is extremely frustrating and inconveniencing. What is Absa thinking? At least give customers a choice if they want to use this service or not!!!! Please can you sort this out asap.
