PATHETIC SERVICE FROM MTN ONLINE

I APP**** FOR A DATA BUNDLE ONLINE ON THE 26/11/18 , AND RECIEVED A RESPONSE SAYING THAT I WOULD BE CONTACTED WITHIN 48 HOURS. I EVENTUALLY GOT A CALL FROM A MTN AGENT ON THE 12/12/18 , WHO HELPED ME TO GET A DATA ONLY DEAL AS WELL AS A LAP TOP CONTRACT THAT WAS ON PROMOTION , ALL THE QUESTIONS WERE ASKED AND ANSWERED AND I WAS TOLD AS THIS IS A ADDITIONAL CONTRACT AS I DO HAVE A EXISTING CONTRACT WITH MTN THAT I HAD PLENTY OF FUNDS AVAILABLE AND THAT EVERYTHING WAS APPROVED I WAS THEN TRANSFERED TO A SUPERVISOR WHO ALSO ASSURED ME THAT EVERYTHING HAD BEEN APPROVED AND I WOULD GET DELIVERY WITHIN 3 TO 10 WORKING DAYS ONLY TO GET A SMS TODAY TELLING ME THAT THIS APPLICATION HAS BEEN DECLINED . I WOULD LIKE TO KNOW WHAT KIND OF ONLINE SHOP DO YOU HAVE IF THE AGENTS CALLING SAY ONE THING AND CAN APPROVE EVERYTHING WHEN IT STILL HAS NOT BEEN APPROVED ? AS WELL AS WHY DOES IT TAKE SO LONG FOR A AGENT TO CALL BACK ? WHEN I TOOK OUT MY INITAL CONTRACT I EXPERIENCED THE SAME SORT OF SERVICE WITH THE ONLINE STORE BUT THOUGHT I WOULD GIVE THEM A SECOND TRY , AM REALLY REGRETTING GOING OVER TO MTN NOW
