Drop Calls

I've been getting about 10 -15 dropped calls a day on my VIP RED Contract with Vodacom on a Iphone 7. I called and reported this more than once to the 082111 call centre with getting a reference for my call even after i've requested it. One of the network centre agents called me and advised that Vodacom can't fix this and that I need to change my network setting to use a "slower network". I did not take out this contract on the basis that I will only get limited use of the network to ensure that I won't get dropped of failed calls. Tonight I called Vodacom again and to explain my whole problem to a new agent because nobody that i've spoke to gave me a reference on sms or email that I requested and confirmed with the relevant agen that he will provide it. I think this is totally unacceptable. On a busy day in my transport company I make and receive about 200 calls. It's really embarrassing to apologize to my customers and driver because Vodacom lets my calls drop - really unprofessional to do business like this.

Please can Vodacom fix my Problem before I advertize the screenshots of all my dropped calls on all social media platforms that is available to me.
