Disgusting service

I tried to call vodacom accounts to query a billing amount on my one number that is data line. It took me over 30 min to get to the right persons. As every person transfered me to someone else. Needless to say, I did not get any assistance. I wanted to cancel that number but was advised not to cancel but move to a 5gig data. I then did that and was told that the cost will be R79 a month. But only to find that I am also billed for a Comp Laptop&Tab Ins(R1501-R2500), which I did not know of and did not order or even received. This is disgusting that been a contract customer with vodacom for almost 20 years and the *********** service that I have received. I have already 3 numbers that is finished with the 24 month contract and the 4th is almost finished. I will take my business elsewhere one this number has reached the end of the contract.
