Bad Vodacom signal in Milnerton Central

The signal in respect of Vodacom is rather bad in some places in Milnerton Central, which is rather unexpected, considering that it is part of a large city such as Cape Town, and only 5km away from Century City, where 5G is even available. Some days if I need to use my phone as a router for work purposes, there is not sufficient signal to sustain a proper connection, whereas sometimes there is no signal at all.

Would it be possible to investigate this discrepancy, as this data connection is crucial for the purposes of my work during the course of the day and causes me many delays if not working properly.
