Worst service!

On the 4th of January 2018 I lost my cellphone, so since it was insured under Jets stored in decided to file a claim. Upon my arrival at Jets stores I was instructed to block my simcard with Vodacom and then Vodacom instructed that I get into contact with RMCS to authorize a swim swap and purchase of a sim, then they sent an email proving that I am their customer and I can do a swim swap. Everytime I go to vodacom they said I must do a letter of authorization, then it was done. When I went again with the letter the Vodacom cellular shop said they cannot do it since RMCS owes them money. So again today, on the 9th RMCS said I must purchase a simcard at vodacom so they can do the swim swap, countless times calling they keep saying I must not use the sim yet, they will contact me but till this hour they haven't. I'm sick and tired of waiting without a simcard, and not being able to be in contact with my number instead at such an old age I have to deal with nonsense service. I want this sorted, I'm not even compromising or willing to wait any longer.
