Terrible service customer AXXESS!!!!

CELL C Fixed LTE: When it's working, it's excellent, but that's if it's working. Latest issue is that for the last 5 days my account keeps of stating I've reached my monthly cap. This is weird since my router show only ~68GB data used currently same as the customer login portal. With 52GB remaining. I have the 100GB package, today was the fourth time I had to call the call line and the second time they tried to reset my account with a 5GB topup. The first two times talking to the consultants they said there was a network issue. The 3rd time they said my account needs to be reset and the 5GB topup was done. Worked fine for 2 days, but today I tried to use the remaining of my data as it expires at midnight. When phoning the consultant today my call was dropped 4 time using different phones. I finally got hold of someone and they said the usage stats must be incorrect.. 30-50GB incorrect, I highly doubt. Either way, he then added 5 more GBs to my account and told me he'll investigate on IS side and get back with a solution/answer. It's been more than 4 hours with no answer... Guess ISP of the year isn't in the bag for them this year.
