Hello Cat_Jane48,
Welcome to the community!
Sorry to hear your phone is being bombarded with ads. There are some decent ad-blockers available from Google Play which may help.
With regards to your amount of available data, it is possible to have already reached your data allotment if you just activated services. You should note that your billing cycle would not usually start until a few days after you activate services. As such, any data allotments and monthly costs would be prorated for the few days before your billing cycle starts (see here). So, in theory, your daily allotment of data would be 60 GB ÷ days in month. In your case, that would calculate to roughly the amount of data you noted (1.94 GB).
If you only have access to that amount of data, it's possible your billing cycle would start tomorrow and you should have access to the full 60 GB in your plan at that time.
It should also be noted that first bills are of often higher than expected due to the inclusion of prorated fees for the first few days of service prior to the start of the billing cycle.
You should note the forums are community-driven and not intended as a venue for customer services. We do not have access to customers' accounts. If you wished to discuss your situation, you would need to contact customer service. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
