No reception

We operate a Guesthouse in Polokwane. Lately everyone uses cellphones for communications and all other services related to banking,security,operational and a lot more. Unfortunately i do not have good reception since October2016 in my area.Possible duo to the upgrades done strengthening transmission signal to 4G.. my reception went from very good to zero as you reduced the signal footprint to strenghen the signal.Maybe your towers are underdesigned to host more equipment i do not know but something seriously are wrong. I have absolute no reception inside the Guesthouse and in times like this whenever i have a security problem i have to go outside my property to phone the SAPS or security company.Thats very risky indeed ! I can not do any business at all as i do not have any reception ! I am loosing bookings and income.Surely this is a breach of contract as well ? I phoned Vodacom customer services and it was one hell of a mission to get the massage across.I eventually got hold of a senior person who promissed me to send technicians to me as this is "strange" to them.Nothing happened. I phoned again and a lady quit senior as well promissed to act maybe install a booster or something.Nothing happened i phoned again she the admit that my complained are logged on the system and promissed action. After a couple of months Vodacom phoned and asked if i still have a problem and if the technician came to my propperty,i said not at all and that was the end.This issue is not resolved after ± a year now and i am loosing income and my security are at riskk. I joined a CPF group and bought a two way radio as well.Please Vodacom we supported you in the beginning we put you on the " map" we helped you increase your footprint...all i ask, is help us to get a decent reception for the more than R35,000.00/annum we spend on you VODACOM for more than 10-15 years actually since cellphone inception way back in the 90"s.Please sort out this issue Vodacom.
