Cambelt broken!

Cencar Bosch replaced the Cambelt on my Audi A4 on 171816Km. 08/02/2013 Tax invoice 28501.<br> <br> On 6 September 2015 and on 205300km the Cambelt broke resulting in repairs costing me thousands!<br> Cencar has been a thorn in my side with this car. Their service is pathetic and they are not worthy of operating under the Bosch flag. Or maybe Bosch has such low standards that this is acceptable to them.
