Dishonest Establishment

This is one of the most pathetic and ************* establishments i have ever had to deal with. I was given incorrect telesales information upon upgrading my mtn contract. Incorrect debit order values where taken of my account for 3 months. After me bringing it to their attention 3 weeks ago it was established that the telesales agent was incorrect and a credit would be due to me. Every time i call the call center im given different reasons as to why or when i will be credited. I called on Monday the 22nd of August and was told that it would be processed by Thursday the 25th of August. I called to follow up on this payment this morning and was now told it will be approved and only paid next week. This is absolutely unacceptable that i am having to chase after this credit which is rightly mine to begin with. I will be opening a case of Theft against this establishment and posting this review all over social media so that people know that Mondo is a bunch of dishonest individuals
