MTN deals with MobilesPlus

Be very careful of MobilesPlus. I was called by them at the beginning of December 2018 and told that they could upgrade my MTN contract. They offered me a Note 9 that I was still waiting for upto today. They already had all my details, call and data usage, knew what contract I was on and that I was due for an upgrade. They told me that i would get the phone in 7 - 14 working days. I was called again at the beginning of January where they advised that the consultant had not completed the verification hence they required further details. I was appalled at the service as I had already waited a month. I asked that a supervisor call me however have not received this call to date. I verified the additional details and have been waiting for the phone until i called today where i was informed that they cancelled the contract as the deal was not available any longer. My queries below are for MTN and not Mobiles Plus as they have already proven sub-standard in my opinion. MTN, is this the calibre of company that you use to promote your services and is this how you accept for established customers to be treated? MTN how do you continue relations to such companies that expose your customer base to be messed around? This to me does not show appreciation for the support given by long good-standing customers. MTN how do you respond?
