Jet Store and VVM Attorneys POOR customer service

I'm writing this pathetic service my wife and I received from Jet Stores and VVM Attorneys that are dealing with payments on behalf of Jet Clothing Store. I personally paid off my wife's account in November 2019 and since then we've been struggling and begging for a paid up letter so that Transunioin can Update my wife's profile. Because of VVM and its poor Pathetic call agents that's been making empty promises to provide us with the final letter since. We have made a follow up on 15th of April 2020 and was given reference ***5,Jet ***, still no letter received of empty promises again we followed up and was given #Ticket ***. In 18th of May 2020 Dineo, Zanele promised that we will receive the letter after 21 days. Still no letter received. Another failure of SLA. We followed up again today 9th of June 2020 and got an email response that the matter has been referred to relevant department but no one gets back to us. CAN SOMEONE PLEASE ASSIST HERE. I MEAN BIG NAME COMPANIES LIKE THIS THAT'S PROVIDING SUCH POOR CUSTOMER SERVICES, THAT'S UNACCEPTABLE...
