SBSA mobile - level of incompetence

The incompetence of SBSA mobile is exhausting.

For 6 months, they are unable to allocate my data by the 9th of each month in accordance with my ucount Tier level. I have had to follow up with them each time to sort out (takes about 2 weeks each time). No one solves the problem, and merely tries to pass me on until next month. Wonder how they would react if I didn't pay for 6 months... probably reposes my car.

Emails are not read and comprehended, replies takes over 6 days. No one wants to give me the details of a senior who has the authority to solve the issue. So management just hides behind anonymity. Just hollow apology after apology without resolution.
