Vodafone / 1100 tablet that has been serviced 3 times without success

My cell phone number is [protected] and the ID number is [protected]. I am currently using Vodafone VFD 1100 Tablet on top-up contract from 02 June 2018.

Problem: It is absolutely frustrating that this tablet has been booked 3 times for one and the same problem. Now I am sick and tired of playing hide and sick - I am not sure if it is Vodacom or Gateway Vodacom Service Centre to blame in this context.

Solution: I propose to cancel Vodafone VFD 1100 Tablet top-up contract so as to enable me to return to the normal smart phone top-up contract which I have been having and enjoying from June 2004 seeing that the device will a piece of second gadget.
