Phathetic service from Vodacom contact centre

This company does not value its customers lately. I've been with Vodacom for more than 16 years on contract to contract. Been trying to get assistance with upgrades and updating of banking details since late June till this day without a luck. When dialing 135 the call goes through Business support services which they are unable to assist. I get directed from call to call to rather rude and unknowledgeable consultants. Now i keep receiving this automated call reminding me to settle my account. Worse their business hours is from 8 to 17pm. It's high time i take my business to MTN
