Vodacom poor service as usual

Just bought my new Huawei P20 Pro and decided to make sure it is well protected. Bought the necessary glass screen protectors. Within the 1 st week the protector has cracked. Went back to vodacom to show them and they were not interested in assisting me. I just feel that I spent a lot of money buying to phones with all the extras and they could at least replace the protector at their cost
