Telkom in waterfall mall..***********

I have recently upgraded my contract at telkom waterfall mall..the service there is good but the only bad thing about telkom in waterfall mall is that they don't have stock in store every single time..it's been 3 weeks waiting for my upgrade package which is a huawei phone and huawei smart watch..and I need to understand that they don't have stock..I have given them enough time and I actually feel like canceling everything..why doesn't telkom in waterfall mall not have stock everytime..maybe it's best we take our business else where,where we won't have to wait for weeks to receive stuff
