No response Vodacom

Very poor service from Vodacom customer care call line. I have been trying for the last 4 hours to speak to an operator to report ********** calls and sms, but no answer as high call volumes experienced . I then went to the Vodacom shop in Fountains Mall Jeffreysbay where I was also met with the same nonchalant attitude. After waiting in line for 20 minutes I was told to phone the customer care line. I have been a Vodacom client for more than 15 years but will definately not renew my contract after expiry.
