****** data and rude call center agents

I bought 5 G data at Vodacom on the 23/03/2019 my data dissapeared on 25 my data was less than 1 g when I called vodacom they refunded the 5G the same thing happened again 2 days later when I called the call center the consulted was very rude and not helpful at all and he told me its due to me being on line for more than 5 hours and when I explained to him that the same thing happened before he insisted that it did not which imp**** that I was lying and when he later realised that it actually he did not even apologize and he said it must be my problem he was very rude and to make t worse he did not even escalate my case which he said he would when he had argued with me for more than 10 min when I called a few hours later cus I was expecting an sms to inform me that my case was reported to the relevent department he did not a log a case he even told me the matter will be resolved in 7 working days whiles the 1st consulted when it first happened told me 48 hours. Vodacom has given me the worst experience not only does their data gets ****** their called center agents are rude as well maybe they don't value our business at all
