Loss of fibre signal

I experienced slow connection and contacted Vodacom. I was provided with a link to do speed tests and this was done 3 times. No one responded and I had to call several times. Then suddenly after they tried to reset the router, the line is now completely down with loss of signal flashing on the router. Been trying for days now to get the line back up. Vodacom informed me that Openserve will make contact which was not done. I called again and they told me that Openserve tried 3 times to call me without success. Needless to say, it was not the correct number they tried as it was a landline number with 021 code and I am in Pretoria. I am still waiting for a call and the contact centre can only escalate the matter and nothing else. Have been a Vodacom client for more than 20 years but this will end as soon as my contract expires. Please do not even bother with your automated response that someone will call me, it means nothing. Vodacom is the worst service provider ever.
