O2 will be doing something about it, you just don't know what that is @Mallemok.
There can be many reasons why a mast can take time to be repaired including:
1. Site access. Most masts are on private land and o2 have to request permission to access on many older contracts.
2. Parts are expensive, sometimes costing tens of thousands of pounds, you will appreciate they don't keep many in stock just in case.
3. Many faults are outside of o2's control. In one case recently a site was down for months due to a water leak affecting electrical access. Little o2 could do.
4. Fibre networks. Much of your phone use travels down the fibre networks so if BT or Virgin Fibre are having issues that will impact on your service.
5. Engineer capacity. Recently a number of engineers were despatched to Scotland due to bad weather conditions there, which can impact on repairs elsewhere.
Whilst these and other examples don't solve your issue, it might help to explain why a repair might not be instant.
Have you tried TuGo? (Assuming it is available for the o2 service you use? )
