Poor customer service

To whom it may concern I Ms J Patterson contacted Cell C on the 10 of September for my cell service was suspended I was asked to send proof of payment which I did on the 11 September my service was still suspended when I phoned once again my service was activated on the 12 September and was once again suspended on the 18 September phoned once again and there reply was they did not receive proof of payment which was payed on the 1September already this is not the first time its happened I am very disappointed in the poor customer service given by cell c in these numerous occasions. @Cell C @Douglas Craigie Stevenson
