No communication from service department

I have had my Car since 2007 (Mazda 3), today I had to call the service department in Midrand ***) several times to ask them to call me back on when I must bring my car in for service<br> <br> I have got no reply no call backs, when I call, they make me hold the line for way too long.<br> <br> I have been a valued costumer to Mazda, after today I have realized the level of service I have received and it is poor. I doubt I will do business again<br> <br> This is not my first complaint on the Midrand branch, if you look at your records I had a poor service due to lack of communication from them (This was in Aug 2015)<br>
