Vodacom bad service

I went to apply for a data contract on the 28th August 2019 at the Vodacom shop in parow centre. I was made to fill in the forms provide them with my bank statements and copy of payslip. The agent that was assisting me by the name of Imran Jaffer promised to give me a call the following day. I waited for the up until I decided to go find out what is the progress on the 3rd September 2019 only to find out that there's a part that he says I didn't sign but by the time I was at the store he double checked the form and assured me everything is in order. I then went and waited up I decided to go to the store again on the 10th September 2019 only for Imraan to say sorry man your application was declined due to TransUnion without him even taking my ID to check on the system. All of that information he was shouting infront of other customers who were waiting for him for a long time. I then insisted that he must take my ID and check on the system and show me the decline reason, only to find out that my documents have not been received at head office and that my application is still pending. I then told him to call the head office so that they resolve the matter only to be told it has been escalated I must wait for the outcome. I have never been so furious in about a service that was given to me but the agent at that store gives pathetic service. I also discovered that the 3 other people that I was waiting with were also angry with his service
