Blocked from calling the Vodacom Call centre - to complain about no signal (again)

Its now been a years since complaining about Vodacom connectivity and poor service! Its been a headache, a dog show, and NO support at all. The last 2 months have been more hellish than normal! 5g tower with no signal, 4g tower with 2g signal (if lucky) and noooo one getting back to me at all with resolutions....nothing! I get a phone call yesterday (9 Sept 24) saying the towers are fixed. BUT NO!!! THEY ARE NOT!!!! We are getting less than 1mbps on the 5G line!

This is the best part....as if its not good enough already! I try to call this morning to report that the technician was wrong...and Im BLOCKED!! IM BLOCKED ON THE VODACOM CALL CENTRE AS I HAVE MADE TOO MANY CALLS AND THEY ARE PROTECTING THEMSELVES FROM *****?? Now...what am I supposed to do ? Went into the branch and they can do nothing except log again on the system someone needs to call me and sort this ^%$^$^% out? But I know thats not going to happen!
