VODACOM POOR SERVICE

I have had the worst experience ever when the vodacom fiber department on *** its been 2 weeks since my internet hasn't been working properly and i have to keep rebooting it i call them they said they fixed the settings on the router and it started to work gor that day only! . So today I decided to call them again, the first call was at 09h17 and held on the line for 15 minutes then got transferred back into the queue. Then i called for the second time and while speaking to the consultant, the, then a recorded message said i had to call back again due to high call volumes and the call dropped!!!!!!!!! WHICH COMPANY DOES THIS!!!!!!Then i called back and after 30 minutes of trying to get through Athi Duduma answered thenl call, i first requested to speak to his Team leader, he advised his Team leader by the name Sibo is not available and he cannot provide any contact information for him. I then asked to speak to another Team Leader on duty, which was Fazel, but Fazel never ended up taking the call. Every time i asked Athi to transfer me through Fazel i was put on hold and Athi came back on the line giving excuses. Please can someone from vodacom call me back and get my network issue sorted!
