No signals again

We are fed-up - reported this 3 weeks ago - call center phoned and said they will monitor - signals almost gone again - no load shedding - can not pass the bug. we HAVE ALMOST NO DATA SIGNALS - If we phone the signals just cutts off - We are really having 6 contracts with Vodacom - but If you want to see us transferring to another service provider - give us this utterly bad service!!! *** my data line nr - but on the account is another 5 contracts!!! Cell C will receive all my contracts if this is Vodacoms attitude!!!!!! Correct your signals and give us what we are paying for
