MTN WiFi Data Signal for past month picking up EDGE instead of 3G or LTE in Milnerton

At the beginning of November for some or other reason I started experiencing bad signal at my home in Milnerton on my MTN Data, only receiving EDGE no LTE or 3G.Prior to this for the past couple of months I had no problem with MTN. After checking Cell C WiFi and Vodacom WiFi which gave me LTE and 3G.I phoned MTN customer care. The consultant made me change several of my mobile networks settings including the mode and added additional APN name.This made no difference. If I take the device and sim to work which is in cape town I do not have the same problem.I reported this back to customer care and was told that this will be forwarded to the coverage team.I then went into MTN store at Canal walk and the consultant checked my settings and reverted back to the way it was. on 8 November I sent an email to customer care REF ********** 5. The response I received via email " network tower 1393 Unicorn Container Lines is currently being remotely accessed by our network technicians, please monitor for a few more days and advice if problem persist - we apologize for the inconvenience caused ". This is now a month later and this morning I phoned the coverage team and the lady I spoke to could not find the previous ref no it appears the call was closed without resolution. So now I have a new ref no ********** 0. So I am not holding my breathe, but I would like to know how MTN plans to resolve this.
