Database Input Skipping Rows

So I have two functions, one that add customers and one that deletes customers to a .mat database. When the cell is empty and a customer is added, it starts at 2 (which is understandable), but when a second customer is added, it jumps to 7. I'm not quite sure why it keep doing this.
fprintf('\nPlease provide the following:')
customername = input('\nCustomer Name: ','s');
customerphone = input('Phone #: ','s');
customeraddress = input('Address: ','s');
customerpoints = input('Loyalty Points: ');
load('customerDatabase.mat');
C = length(customerDatabase)+1;
customerDatabase{C,1}=C+1;
customerDatabase{C,2}=customername;
customerDatabase{C,3}=customerphone;
customerDatabase{C,4}=customeraddress;
customerDatabase{C,5}=customerpoints;
save('customerDatabase.mat','customerDatabase')
input('Loyalty Customer added! ...Press ENTER to continue...');
Output:
customerDatabase =
[2] 'Test 1' '111-111-1111' '11 111th St' [ 111]
[] [] [] [] []
[] [] [] [] []
[] [] [] [] []
[] [] [] [] []
[7] 'Test2' '222-222-2222' '22 22ns Ave' [22222]
Press ENTER to continue...
Then if I try to remove customer 7 using
load('customerDatabase.mat');
customerDatabase
removecustomer = input('Which Lolalty Customer would you like to remove? (enter customer#): ');
for i = 1:length(customerDatabase)
if removecustomer == customerDatabase{i,1}
customerDatabase(i,:) = {[] [] [] [] []}; % delete row i from cell
emptyCells = cellfun('isempty', customerDatabase);
customerDatabase(all(emptyCells,2),:) = [];
for i = 1:length(customerDatabase);
customerDatabase{i} = 1 + i;
end
save('customerDatabase.mat','customerDatabase')
input('Loyalty Customer Removed... Press ENTER to continue...')
It completely changes the array to output this when I view the content of the .mat database:
customerDatabase =
[2] [3] [4] [5] [6]
Any help would be greatly appreciated.

Instead of trying
C = length(customerDatabase)+1;
Try :
C = size(customerDatabase,1)+1;
