Poor Service

I have been loyal customer to MTN many years and I reached my boiling point. On the 24/12/2018 I received a call from Mobile Plus offering me a package that I could not refuse. The package consisted of 50 gigs of data; 1000 minutes to mtn numbers; 50 minutes to any network and additional 500 mb of data. I accepted the offer and I was told within 7-14 working days I would receive my new mobile devise and upgraded package. I called Mobile plus on ********** 256 several occasions just to be told that there is no stock of the Samsaung 5 J phone and I must be patient. My current phone devise is damage and I am unable to view anything on the screen. I went to the MTN store at Somerset Mall to pay my bill for MTN to tell me that my deal was cancelled but when I spoke to Mobile plus previously MTN is waiting on stock. I called mobile plus this morning and I was not able to get through as they are on holiday. As a client I am disgusted the way I have been treated and when I spoke to Mobile plus previously I told them that I will go on to hello peter and response was never minded.
