Worst service ever

I received the worst service from telkom express in Cresta.... I app**** for a contract for a cellphone and a laptop with sales agent Tshepang Filicity Maamogwa... Firstly in the store she advised that it was approved. I waited a whole week for a response and no feedback.. I went in store and after waiting forever the store manager sandy advised that I needed to redo the application and had to wait another week as a credit vetting needed to be done... Although the items I app**** for were in the store... I couldnt get any of the items as the process was not done correctly first time... After another week I then received my items... Sim cards were activated in store... Upon arriving at home I noticed that I was receiving banking notifications from capitec.. I called the store they advised I was given the correct number.., I even had to call capitec to find out who's number it belongs to.. I then found out that the Sim card I was given by Tshepang Filicity Maamogwa was a prepaid and not contract and it belonged to a different client.... I then had to return once again to the store and all I could get was I'm sorry and a broken promise.. Tshepang Filicity Maamogwa promised she would compensate me for all the inconvenience caused.. Till today nothing happened... I'm really not happy with the service as I had to waste petrol by going up and down to the store for someone else's negligence... And all they can say is 'sorry'.. Very unhappy
