Upgrade of my business site

I have app**** for an upgrade of my place to 60 Amps on 31 December 2018 as I am conducting business there and I was only provided 20 Amp. On 31 January 2019, I had to go to Eskom and beg for an invoice so that I could pay for the upgrade I app**** for. I paid R10 166 and got confirmation by SMS the same date at 20:01 with reference no. ********** 48. I have since been following up with Eskom as to when are they upgrading my place and to date, nothing has happened. All I am getting is SMSes saying "wait for the contractor". Their records are on 08 Feb, 15 Feb, 18 March and 18 March 2019. I have since made telephone follow ups and sent numerous emails to Eskom Customer Service on 01 Feb, 06 Feb, 15 March, 26 March, 02 April and 07 April respectively. I do not know what to do now as this inconvenience is affecting my business very badly because without electricity, I cannot satisfy my clients and them leaving me means a loss financially. Can hellopeter please help me resolve this impasse as I have ran out of options now and my business is suffering. I have sent my assistant to Eskom Polokwane on Friday, 05 March 2019 and he was just told that there is nothing they can do whereas customer service always refer us to them.

Please help!
