Just excuses with no service

Mweb use to be one of the greatest service providers, I have been with them for years, no problems until a month ago. The recent problem started 18 February 2021, when I asked to have my 120gb package upgraded to a 220gb package. I received an email on 18 February 2021 saying that my 220gb has been activated. Since then I do not have any day data, been on the phone with mweb since the 18th trying to sort this, but just get transferred from department to department, I was even told the manager will phone me, still waiting for a call, but still no internet. I get excuses like the problem is with telkom or that I am still on 120gb package, they can't access telkom to check, excuse after excuse but nothing happens. My business has been standing still since the 18th as my phones was voip ported to mweb. So no one can phone me. I am tired of the excuses, I want a solution.
