Lazy customer service

I upgraded my one line for data deal with laptop over a month ago to date no delivery or response from Vodacom when I call to inquire I get whole runaround with no clear answers, today I decided to cancel my contract the I was told another they would get back to me in 30min no phone call at all is this the type of service Vodacom offers clients after 20 years being with you further more I also inquired about upgrading my cell I put in a request also month ago again no response sorry to say Vodacom your standards are slipping badly I am sure there are other providers willing to offer me better
