Horrible experience

I had a windscreen replacement *** which was approved on the 12th of Jan. I chose Alberton Pg glass as it is the closest branch to my workplace. I struggled to get a hold of them until the 15th of January because to their unreliable call centre which made me hold to up to 30 mins at a a time. I was promised that my glass will arrive by the 18th of January and that I will be called to be notified when this happens, sadly that call never came and I again had to bear the brunt of the call centre. I eventually got through on the 22nd of Jan where I was promised that my glass had arrived but due to my work schedule I wasn't able to go to the branch and I was told they would send my glass to their mobile crew who would contact me by the 25th of Jan to arrange the fitment. To my disappointment that call never came and I am still here frustrated driving around with a cracked windscreen while my insurance claim is approved, that is just not fair and I deserve better service as customer!!
