Medtronic South Africa

I sorry I bought the Medtronic CGM system. The sensors really last 7 days, while their competitors last 14 days. Having the faalty sensor replaced was a simple process, just send an email with the sensor details and it was replaced within a few days. Now one has to phone the Helpline, which is aways busy, only available during office hours. Usually the line is dropped and one has to phone again, Medtronic service is Terrible Nor can log a compliant on their wed page, no option exists
