Account locked and cannot purchase new contract

In the mid January i received a call from Mondo Mobile whom said they are partner with Vodacom and I was offered a 5G package for R99. I postponed the contract a couple of times to speak to my fiancé so we can agree if we can both have the offer. On 5th February, I received another call from Portia (Mondo Mobile) and concluded the two contracts. She explained that my cellphone will be converted within 24 hours (which was done and happy with) and she said i will also receive my fiancé's starter pack with the couriers in about 7 - 14 days.

We saw a Vodacom special at Dion Wired in which they give two iPhone 6 for R399. We decided to take the special. On 16th February, we visited the retail shop and we were told that our application cannot be processed due to a cancellation of a contract. I explain that i had not cancelled any contract and that i am actually waiting for a delivery for the 5G.

Tuesday, 19th February, I called Mondo and spoke to Astin Pillay who explained that my other contract was cancelled due to affordability. I asked how is it that I was paying Vodacom about R365 every month and never missed a month and that they saying I cant afford R198. I told them that I was not happy with their services and they should have told me that my contract was not approved and that all this is causing friction in the house as expectation for my fiancé's 5G has not been delivered.

I asked if they are going to correct this and he said that he cannot go against the system (ITC) and that I cannot be approved due to affordability. I then requested a cancellation.

My issue is that, now I am unable to purchase the two deal phones from Dion Vodashop due this inconvenience. The special will be ending on the 6 March and I am told that i need to wait for 30 days before my account can be cleared. I do not have 30 days as the special will end soon and need someone to correct so I can proceed with my purchase.

I AM VERY UPSET AND NEED THIS TO BE DEALT AS SOON AS POSSIBLE!
