We were contacted about the Explora deal with On Air and we thought it was a great deal for R150 per month and we have the Explora, the consultant took all our details and banking details, it has been more than 3 weeks and nothing, not a sms or a call, everytime i phone they say it will be delivered within the next 3-5 days ...maybe then next year we will get the product!!!! I think this is bad service and as I was phoning them AJust now they told me sorry their systems is off i must phone back in a Hour???***>>>BAD SERVICE BAD BAD BAD
